[PR libgomp/65742, PR middle-end/66332] XFAIL acc_on_device compile-time evaluation

The OpenACC 2.0a specification mandates differently, but we currently do get a
library call in the host code.

Backport trunk r224028:

	PR libgomp/65742
	PR middle-end/66332

	gcc/testsuite/
	* c-c++-common/goacc/acc_on_device-2.c: XFAIL for C, too.
