Fix 'libgomp.oacc-fortran/parallel-dims.f90' for 'acc_device_radeon'

..., by simplifying 'libgomp.oacc-c-c++-common/parallel-dims.c', and updating
the former correspondingly.  '__builtin_goacc_parlevel_id' does the right thing
for all 'acc_device_*'.

Follow-up to commit 09e0ad6253f4330977e1b2f116b5e289dc2c2a02 "Update OpenACC
tests for amdgcn".

	libgomp/
	* testsuite/libgomp.oacc-c-c++-common/parallel-dims.c: Simplify.
	* testsuite/libgomp.oacc-fortran/parallel-dims-aux.c: Update.
