[LTP] [PATCH 5/6] memcg_lib.sh: Remove subdirectories in cleanup

[Cyril Hrubis]

Some tests create subdirectories in the memcg directory created for the
testcase, namely the move_charge_at_immigrate ones. Hence we need to
remove all subdirectories before we attempt to remove the test
directory. Otherwise the test will not clean up properly on TBROK.
