changes:
- don't try to set gnss-share socket in geoclue
- install Alsa UCM configs from purism
Upstream ucm is broken when migrating from the purism ucm, so let's
just use ucm from purism until someone upstreams something that works.
What I upstreamed was based on an older ucm from Purism, what they are
shipping is more correct than upstream ucm...
This reverts commit 70b7813fee.
