Description of problem:
mpg123-plugins-pulseaudio now has a:
Supplements:    pulseaudio%{?_isa}

This is bad in 2 ways:
1. It will drag in mpg123 (the main package, i.e., the command-line player), and with it mpg123-libs even if nothing else on the system uses them (in particular, if the GStreamer1 plugin is NOT installed).
2. Installing mpg123 (the main package) on an existing system without mpg123 will NOT trigger the Supplements because it is not related to mpg123 in any way.

Please use:
Supplements:    (pulseaudio%{?_isa} and mpg123%{?_isa})
on Fedora instead. (This is not supported in RHEL/EPEL, unfortunately.)

Version-Release number of selected component (if applicable):
mpg123-1.23.8-3.fc25

How reproducible:
Always

Steps to Reproduce:
1. Try to compose a F25 kickstart with updates enabled
2. Check the packages it includes.

Actual results:
Includes mpg123, mpg123-libs and mpg123-plugins-pulseaudio.

Expected results:
Does not include mpg123 and mpg123-plugins-pulseaudio. Either does not include mpg123-libs either, or includes gstreamer1-plugins-mpg123 and mpg123-libs, depending on whether gstreamer1-plugins-mpg123 gets added to comps or not.
