testsuite/libgomp.c/usleep.h: Use sleep-loop also for GCN

As typically configured, newlib's libc.a does not build 'posix' and,
hence, usleep is not available. Thus, use the same fallback as for nvptx.

libgomp/
	* testsuite/libgomp.c/usleep.h (fallback_usleep): Renamed from
	nvptx_usleep; use also for device={arch(gcn)}.
