meson: add options to set server and client RT priority

Browse source 
Make a rtprio-server and rtprio-client option. Leave the server
priority by default to 88 but lower client priority to 83. JACK
does something similar by setting clients to rtprio-server - 5.

Make module-rt use the client priority by default and bump the server
priority explicitly in the config file.

Leave the pulse-server to the default rtprio-client, there is no reason
to lower this any further because it is really just a regular client.

Bump the ffado packetizer thread to rtprio-server + 5 because that is
also what JACK does.

88 is still much higher than the value of 60 that JACK uses in
Fedora but now this is at least configurable.
