libpthread_db: undo the memset size change.

I inadvertedly soubled the size of the memset without noticing the
start address had changed. The size for the memset in pt_map_thread()
shouldn't actually match the reallocarray() so undo that part of r317200.

This is a re-commit of r317201 to clarify the log.

X-MFC with:	r317200
