libpager: fix notify_port_t receiver lookups

This fixes one more occurence of a notify_port_t receiver lookup that
I overlooked in 5a4926dd52aed56913cbe10592063ff0da753700.

* libpager/no-senders.c: Include "notify_S.h" so that the compiler can
spot such mistakes in the future.
(_pager_do_seqnos_mach_notify_no_senders): Fix receiver lookup.
