build: wire HAVE_ROPUS

Makefile.common gains a HAVE_ROPUS block following the rmodtracker
precedent, adding formats/opus/ropus.o and pulling in
audio_transfer.o when no other audio decoder already has; qb defaults
it to yes; griffin defines it and includes ropus.c next to the other
single-file decoders, extending the audio_transfer condition.
