Adapt libgomp acc_get_property.f90 test

The commit r10-6721-g8d1a1cb1 has changed
the name of the type that is used for the return value of the Fortran
acc_get_property function without adapting the test acc_get_property.f90.

	* testsuite/libgomp.oacc-fortran/acc_get_property.f90: Adapt to
	changes from 2020-02-19, i.e. use integer(c_size_t) instead of
	integer(acc_device_property) for the type of the return value of
	acc_get_property.
