avahi: bump INC_PR to avoid do_configure failure in existing workdir

When we split S and B for avahi in OE-Core commit
6112a07f4e9865f7ae0e5a953669c1adf789f9f0, files left over in the workdir
from a previous build seem to break re-execution of do_configure. Bump
PR to give a fresh workdir and avoid this problem.
