We support two ways to update the operating system:
- `/usr/bin/rpm` (and `dnf` etc.) where SELinux labels are
computed and written client side
- ostree (and other image-based systems) where SELinux labels
were computed server side.
In the ostree case, I'd like the ability to generate smaller
images that do not even have `rpm` installed.
This hard dependency from `selinux-policy` -> `rpm` is one of
the only main blockers.
RPM supports these "alternative" conditionals, it's easy to do.

If an user builds package with `%bcond mls 0` it ended with
RPM build errors:
error: Installed (but unpackaged) file(s) found:
/etc/dnf/protected.d/selinux-policy-mls.conf
Installed (but unpackaged) file(s) found:
/etc/dnf/protected.d/selinux-policy-mls.conf
With this change, dnf procted files for a policy is installed only when
the policy is built.

/run/systemd/generator is no longer equivalent to /usr/lib/systemd/system.
It has its own rules in the policy now, so instead
/run/systemd/generator.early and /run/systemd/generator.late
are equivalent to /run/systemd/generator.

Instead of plain macros, use `%bcond ...` and `%{with ...}`, which will
allow controlling which policy types to build using the --with/--without
command-line arguments when calling `rpmbuild` or `mock`.

https://rpm-software-management.github.io/rpm/manual/conditionalbuilds.html
Note that the BUILD_DOC macro is removed without replacement as it's
unused. (The builds of the -doc and -devel subpackages overlap too much
for the macro to be useful, anyway.)

As part of https://fedoraproject.org/wiki/Changes/Unify_bin_and_sbin, programs
are moved from /usr/sbin/alternatives to /usr/bin/alternatives. Provisions
have been made to create a compat symlink on traditional systems, so that both
paths work and packages that use paths under /usr/sbin do not need to be
rebuilt. Unfortunately, on ostree systems, the compat symlinks are missing, so
using absolute paths causes problems
(https://bodhi.fedoraproject.org/updates/FEDORA-2024-3aafcac6a8).
There is no reason for or benefit from specifying the full path to binaries in
scriptlets because the scriptlets are called with a well-defined $PATH. When
we drop the full path, they work fine no matter where exactly the binary is
installed.
An additional problem with full paths is that they are specified using macros,
and the macro works fine within a package, but they is no guarantee that
different builds of different packages at different times use the same
definition of %_sbindir.
I also changed /bin/echo → echo. The shell builtin is good enough, we don't need
to spawn a separate process.

Since libsemanage commit d96f27bf7cb91 ("libsemanage: Preserve file context
and ownership in policy store"), libsemanage tries to preserve file
contexts during SELinux policy rebuild. If the underline fs does not
support any operation used, it prints warnings on stderr. Given that
it's not a fatal error, it's reasonable to suppress them.

The commands should always end || : , because by policy we should
ensure RPM scriptlets always exit 0:
https://docs.fedoraproject.org/en-US/packaging-guidelines/Scriptlets/#_syntax
Also, rm is in _bindir, not _sbindir.
This seems to have caused a failed test for an nbdkit update:
https://openqa.fedoraproject.org/tests/2628713#
the live image build failed because of a scriptlet error that
seems to be caused by this:

Using exact NVR dependencies works well within RPMS from a single SRPM,
but otherwise relies on assumptions which do not always hold out.
Because %release includes %dist, this is particularly fragile in the
context of the Rawhide->ELN->c10s build pipeline. For instance, if a
package which uses %selinux_requires gets built for ELN with the rawhide
selinux-policy, then .fcNN will be hardcoded into the ELN build, and the
ELN build with .elnNNN will never meet the condition (since f > e).
