[patch/rfa] Get rid of HP_OS_BUG

[Randolph Chung <randolph@tausq.org>]

In my continuing quest to hunt down all the hppa code scattered all
around arch-indep code, i found this....

HP_OS_BUG is actually not defined anywhere. Looking through the
changelogs, it looks like it used to be defined in m-hp9k320.h. I
believe this is a m68k HPUX machine that is no longer supported, so i
think we might as well get rid of it... unless someone tells me
otherwise i will check this in in a couple of days.

thanks,
randolph

	* infrun.c (trap_expected_after_continue): Remove HP_OS_BUG workaround.
	(proceed, init_wait_for_inferior, handle_inferior_event): Likewise.
