Fix expectation and types in acc_get_property tests

* Weaken expectation concerning acc_property_free_memory.
  Do not expect the value returned by CUDA since that value might have
  changed in the meantime.
* Use correct type for the results of calls to acc_get_property in tests.

libgomp/
	* testsuite/libgomp.oacc-c-c++-common/acc_get_property-aux.c
	(expect_device_properties): Remove "expected_free_mem" argument,
	change "expected_total_mem" argument type to size_t;
	change types of acc_get_property results to size_t,
	adapt format strings.
	* testsuite/libgomp.oacc-c-c++-common/acc_get_property.c:
	Use %zu instead of %zd to print size_t values.
	* testsuite/libgomp.oacc-c-c++-common/acc_get_property-2.c: Adapt and
	rename to ...
	* testsuite/libgomp.oacc-c-c++-common/acc_get_property-nvptx.c: ... this.
	* testsuite/libgomp.oacc-c-c++-common/acc_get_property-3.c: Adapt and
	rename to ...
	* testsuite/libgomp.oacc-c-c++-common/acc_get_property-host.c: ... this.
