Subject: hurd: avoid including hurd/signal.h when not needed

thus making <hurd/port.h> and <hurd/userlink.h> includable without
_GNU_SOURCE.

	* hurd/hurd/port.h: Do not include <hurd/signal.h>.
	* hurd/hurd/userlink.h [!defined __USE_EXTERN_INLINES ||
	!defined _LIBC || !IS_IN (libc)]: Do not include <hurd/signal.h>.
