testsuite ltime_gmtime tweak

[Alan Modra]

I've had this in my tree for years, living as I do in one of the few
regions of the world so backward we have a half-hour timezone.  OK to
apply?

	* gfortran.dg/ltime_gmtime_1.f90: Tolerate half-hour timezones.
	* gfortran.dg/ltime_gmtime_2.f90: Likewise.
