Put the configured server address string in PULSE_SERVER if it appears
to be remote. This should be enough for apps that already have network
access via --share=network.
If remote access to a PulseAudio server has been selected but the app
does not already have the --share=network permission, we don't want to
add --share=network automatically, because that would open up the app's
access to network resources, perhaps unexpectedly. However, users of
this non-default configuration can use `flatpak run --share=network` or
`flatpak override --share=network` to open up that access if they
consider it to be safe enough.
