nptl: Remove sparc sem_wait
This patch removes the sparc32 sem_wait.c implementation since it is
identical to default nptl one.  The sparcv9 is no longer required with
the removal.

Checked with a sparcv9 build.

	* sysdeps/sparc/sparc32/sem_wait.c: Remove file.
	* sysdeps/sparc/sparc32/sparcv9/sem_wait.c: Likewise.
