Avoid running sed on the whole "nm" output and also avoid "sed | awk"
pipe in favor of a single awk call. Overall, this gives around 20%
speedup on some quick synthetic tests:

* find-provides.ksyms: Check presence of absolute __crc_* symbols with
"grep -q" exit code and not presence of sed output; rewrite awk script to match
the __crc_* symbols instead of preprocessing the nm output with sed.
* find-requires.ksyms: Likewise.

It leads to some regressions in requires generation precision, though,
as it is no longer possible to exclude requires that are satisfied
by other kmods in the package. And calling a script on each file (instead
of calling it on the whole file list at once) does not make things faster,
either (so much for "sanity and benefit").
* find-provides.ksyms: Check for "$@" as well.
* find-requires.ksyms: Likewise.
* kernel-srpm-macros.spec (Source104, Source105, Source106): New
attribute files.
(%install): Install provided_ksyms.attr, required_ksyms.attr,
and modalias.attr into "%{buildroot}%{_fileattrsdir}".
(%files -n kernel-rpm-macros): Add provided_ksyms.attr,
required_ksyms.attr, and modalias.attr.
kmodtool: Remove "%global _use_internal_dependency_generator 0".
macros.kmp: Remove %__find_provides and %__find_requires.
* modalias.attr: New file.
* provided_ksyms.attr: Likewise.
* required_ksyms.attr: Likewise.

- Add support for compressed kernel modules to find-provides.ksyms,
find-requires.ksyms, firmware.prov (#1622019)
* find-provides.ksyms: Try to process files whose names end with
something else than "*.ko" by guessing a decompressor and uncompressing
it in a temporary file and parsing it instead.
* find-requires.ksyms (all_provides): Likewise.
Add "(\.gz|\.bz2|\.xz)?" to the end of the module path matching regular
expression.
* firmware.prov: Add "(\.gz|\.bz2|\.xz)?" to the end of the module path
matching regular expression.
