Call real pthread_sigmask instead of its wrapper in start_mark_threads

(fix of commit 95947bdc5)

The wrapper itself does not do anything useful in this case.

* pthread_support.c [PARALLEL_MARK && !NO_MARKER_SPECIAL_SIGMASK]
(GC_start_mark_threads_inner): Call REAL_FUNC(pthread_sigmask) instead
of pthread_sigmask.
