I just realized ECalBackend -- which is where the "cache-dir" property
lives -- doesn't have access to ECalBackendStore.  The derived backend
classes all keep their own private store objects.

So without an API break to make ECalBackendStore just take a filename,
I'm back to square one.

In lieu of an API break I think I'll have to just replicate the path
building logic in ECalBackend, ECalBackendStore and ECalBackendCache.
Not ideal, but still better than all the backends doing it themselves.
