Linux: Report reclaimable memory to kernel as such (#16385) 
Linux provides SLAB_RECLAIM_ACCOUNT and __GFP_RECLAIMABLE flags to
mark memory allocations that can be freed via shinker calls.  It
should allow kernel to tune and group such allocations for lower
memory fragmentation and better reclamation under pressure.

This patch marks as reclaimable most of ARC memory, directly
evictable via ZFS shrinker, plus also dnode/znode/sa memory,
indirectly evictable via kernel's superblock shrinker.
