posixshm: start counting writeable mappings
r351650 switched posixshm to using OBJT_SWAP for shm_object r351795 added support to the swap_pager for tracking writeable mappings Take advantage of this and start tracking writeable mappings; fd sealing will use this to reject a seal on writing with EBUSY if any such mapping exist.
