* Update module_utils.six to latest
We've been held back on the version of six we could use on the module
side to 1.4.x because of python-2.4 compatibility. Now that our minimum
is Python-2.6, we can update to the latest version of six in
module_utils and get rid of the second copy in lib/ansible/compat.
ansible-playbook now works when run with a playbook
that includes a role that includes another role
specified using csv format
Updated one of the roles used in the tests to fix
broken tests - `make test_galaxy` now works
Fixes#11486. Also addresses the problem alluded to in #10620.
