Remove some semaphore.h linknamespace XFAILs.

Roland's recent sem_* changes introduced some XPASSes for semaphore.h
linknamespace tests by removing a non-static variable "mountpoint".
This patch removes the XFAILs for the fixed bug.

Tested for x86_64.

	* conform/Makefile (test-xfail-UNIX98/semaphore.h/linknamespace):
	Remove variable.
	(test-xfail-XOPEN2K/semaphore.h/linknamespace): Likewise.
	(test-xfail-XOPEN2K8/semaphore.h/linknamespace): Likewise.
