devel/libublio: remove *_p.a profiling library

Since a port cannot reliably and easily infer the profiling
configuration from src.conf (the ports framework defeats reading it, and
historically the port had its troubles with that), remove the profiled
libublio_p.a altogether.

Bumps PORTREVISION due to pkg-plist change on most practical systems.
