Disable gdb.threads-hp

[law@redhat.com]

As they stand, these tests are horribly broken.  Someone may want to 
resurrect them one day.  For now, I'm disabling them.  Per Fernando's
early email, I'm going to go ahead and check-in this change.

	* gdb.hp/gdb.threads-hp/usrthbasic.exp: Disable completely.
	* gdb.hp/gdb.threads-hp/usrthcore.exp: Disable completely.
	* gdb.hp/gdb.threads-hp/usrthfork.exp: Disable completely.
