Accepting request 1096888 from home:favogt:lessgdm

- Merge pulseaudio-gdm-hooks into the gdm package. This was previously
  part of pulseaudio.spec, which was fairly complex (dir ownership,
  separate tmpfiles, dependencies) and it also caused pulseaudio.spec
  to runtime depend on gdm. Avoid all of that by just adding it here:
  + Add default.pa
  + Add entries to gdm.tmpfiles
