audiotestsrc: Make audiotestsrc work

Browse source 
This small patch makes audiotestsrc work.

You will need to uncomment the following lines in pipewire.conf

	add-spa-lib audiotestsrc audiotestsrc/libspa-audiotestsrc
	create-object adapter node.name=my-test factory.name=audiotestsrc

If you use pw-record, use --list-targets to find the target id and
record using --target=<n>
