Title: fix paver theming on devstack (SERVICE_VARIANT support)

For @singingwolfboy

When running in devstack, you need to set the SERVICE_VARIANT so that
assets.py knows what environment file to use. Recall that in devstack
we have all our settings in ../lms.env.json, not just ../env.json. So
you need to run like this:

SERVICE_VARIANT=lms paver lms --settings=devstack

Previously you'd get this error:

Warning: could not find environment JSON file at 'lms.env.json'

Note there is no path on the file, that's the bug. By making
self.REPO_ROOT absolute, we can walk up the tree and correctly find
the file, which is /edx/app/edxapp/lms.env.json fwiw.
