common: split _get_hugepagesize into detection and actual query
This helper has two parts -- querying the value, and _notrun'ing the
test if huge pages aren't turned on. Break these into the usual
_require_hugepages and _get_hugepagesize predicates so that we can adapt
xfs/559 to large folios being used for writes.
