Subject: [PATCH 1/4] Use macro error reporting for %add_sysuser errors

Lua has error() but no warning() (obviously) which we'll want in the next
step, so for consistency lets just use macro.error() instead.

Subject: [PATCH 2/4] Fix an apparent thinko/typo in the sysusers test spec

I'm quite sure I didn't really intend to test duplicate files behavior
here...

Subject: [PATCH 3/4] Handle unsupported 'r' and 'm' sysusers types more
 gracefully

People will want to use existing sysusers.d files through rpm and while
we don't support 'r' and 'm' at this time, we shouldn't really call
them "invalid" and error out. Issue a warning instead, and ignore.

Subject: [PATCH 4/4] Fix comment line handling in sysusers.d(8) files

sysusers.d(8) format permits empty lines and commits, and so must we.
Add some extra fluff to the test-case for this.

This is the second half of
https://bugzilla.redhat.com/show_bug.cgi?id=2246236

Fixes: #2741
