This adds support for numa_domains abstract name in OMP_PLACES, also new
in OpenMP 5.1.
Way to test this is
OMP_PLACES=numa_domains OMP_DISPLAY_ENV=true LD_PRELOAD=.libs/libgomp.so.1 /bin/true
and see what it prints on OMP_PLACES line.
For non-NUMA machines it should print a single place that covers all CPUs,
for NUMA machine one place for each NUMA node with corresponding CPUs.
