Restore 'GOMP_OPENACC_DIM' environment variable parsing

... that got broken by recent commit c057ed9c52c6a63a1a692268f916b1a9131cd4b7
"openmp: Fix up strtoul and strtoull uses in libgomp", resulting in spurious
FAILs for tests specifying 'dg-set-target-env-var "GOMP_OPENACC_DIM" "[...]"'.

	libgomp/
	* env.c (parse_gomp_openacc_dim): Restore parsing.
