Fix iterating over pending signals if a signal doesn't have to be cleared 

* sigproc.cc (pending_signals::clear): Yet another fix to fix the fix.
	Actually iterate over the list of pending signals even if there's a
	signal which doesn't have to be cleared.  Other than that, revert loop
	to it's former self as a while loop.
