Fix up the test-paths to be more obvious

There's "magic" in the zaza package that converts charm names to paths
for the charm under test.  However, it is poorly understood, and most
charms use the relative path.  This patchset does that.  Overlays
complicate that picture, but this charm doesn't use overlays.
