Linux 5.9 compat: Update NR_SLAB_RECLAIMABLE to NR_SLAB_RECLAIMABLE_B
This change appears to primarily be a name change for the enum. Had
to update the test logic so that it works so long as either one of
these is present (favoring the newer one). Additionally, as this is
newer, it only shows up in node_page_item, so this commit doesn't
test zone_page_item for the same enum.
