Code review comment for ~ubuntu-audio-dev/pulseaudio:snap-policy-xenial

Testing on a VM, this isn't working correctly. I got the following trying to record when using a snap AppArmor label:

    I: [pulseaudio] client.c: Created 4 "Native client (UNIX socket client)"
    I: [pulseaudio] protocol-native.c: Got credentials: uid=1000 gid=1000 success=1
    I: [pulseaudio] module-snap-policy.c: Checking access for client 4 (skype)
    W: [snapd-glib] module-snap-policy.c: snapd_client_get_snap failed: Not connected to snapd
    I: [pulseaudio] module-snap-policy.c: Access check for client 4 (skype): 0
    I: [pulseaudio] client.c: Freed 4 "parecord"
    I: [pulseaudio] protocol-native.c: Connection died.

This looks like it is due to version skew of snapd-glib. The old version requires a snapd_client_connect_sync() call.
