ci: Revamp to actually run the tests

Previously we were just building in a container, now we actually run the test
script.

This explicitly does builds in a container still, and only installs
the bwrap binaries into the host's `/usr`.  Down the line I think
we can enable better support for this model in redhat-ci.

Closes: containers#160
