Fix pfinet crash

During rsyslog testsuite, it does happen that threads running
schedule_timeout get woken up by something else than the timer.  The (local)
timer needs to be removed in that case.  Let's just always remove it, like
Linux does.

* pfinet/glue-include/linux/sched.h (schedule_timeout): Remove local timer
before returning.
