test_cephfs.py: delete purge_dir() helper method, use rmtree() instead

Use rmtree() instead of purge_dir() for following 2 reasons -

1. purge_dir()'s recursive nature makes it vulnerable to max recursion
   limit.
2. It is redundant to have purge_dir() helper method since rmtree()
   already performs job in a better way.
