storage/posix: Prevent gfid handle leaks

The case which can lead to gfid handle leaks:
Self-heal removes directory '/d' with 10 files in it, in brick b1.
This dir is renamed to <landfill>/<hashval of '<brick-path>/d'>
by posix. Before the janitor thread could remove the directory,
self-heal could remove another directory with same path '/d'.
Then again the rename to same path is done by posix as before.
The gfid-handles of the old '/d', 10 files in it are not unlinked.

To prevent such problems, rename the directory to be removed to
<landfill>/<gfid-str>.
