python/semanage: empty stdout before exiting on BrokenPipeError

Empty stdout buffer before exiting when BrokenPipeError is
encountered. Otherwise python will flush the bufer during exit, which
may trigger the exception again.
https://docs.python.org/3/library/signal.html#note-on-sigpipe

Fixes:
   #semanage fcontext -l | egrep -q -e '^/home'
   BrokenPipeError: [Errno 32] Broken pipe
   Exception ignored in: <_io.TextIOWrapper name='<stdout>' mode='w' encoding='UTF-8'>
   BrokenPipeError: [Errno 32] Broken pipe

Note that the error above only appears occasionally (usually only the
first line is printed).
