[GLIB] Change MPRIS bus name to be sandbox friendly
https://bugs.webkit.org/show_bug.cgi?id=241807

Reviewed by Philippe Normand.

When an application has an ID this changes the name to be
org.mpris.MediaPlayer2.$APP_ID.$INSTANCE_ID which is permitted
by default with flatpak and now with our bubblewrap sandbox.

Instead of the previous org.mpris.MediaPlayer2.$APP_ID-$INSTANCE_ID
which would be blocked by sandboxes unless they allowed an
overly broad org.mpris.MediaPlayer2.* permission.
