hurd: Avoid PLT references to syscalls

	* mach/Makefile ($(mach-syscalls:%=$(objpfx))): Add hidden definition.
	* sysdeps/mach/include/mach/mach_traps.h (__mach_reply_port,
	__mach_thread_self, __mach_task_self, __mach_host_self, __swtch,
	__swtch_pri, __thread_switch, __evc_wait): Add hidden prototypes.
