afr, index: Clean up stale directory and file indices in granular entry sh

Specifically when a directory tree is removed (rm -rf)
while a brick is down, both the directory index and the
name indices of the files and subdirs under it will remain.
Self-heal will need to pick up these and remove them.

Towards this, afr sh will now also crawl indices/entry-changes
and call an rmdir on the dir if the directory index is stale.

On the brick side, rmdir fop has been implemented for index xl,
which would delete the directory index and its contents if present
in a synctask.
