UBUNTU: SAUCE: shiftfs: mark slab objects SLAB_RECLAIM_ACCOUNT

BugLink: https://bugs.launchpad.net/bugs/1842059
Shiftfs does not mark it's slab cache as reclaimable. While this is not
a big deal it is not nice to the kernel in general. The shiftfs cache is
not so important that it can't be reclaimed.
