openstack: get user-data path relative to the sources

The user-data files are in the sources, in the teuthology/openstack
directory. By default the template path being used is
teuthology/openstack/openstack-{os_type}-{os_version}-user-data.txt and
assumes teuthology-suite / teuthology-openstack is run from the root of
the source directory.

If the user-data path is relative, make it absolute based on the
directory in which the openstack module is found.
