bitbake: tinfoil: fix override handling in remote datastores

There was a huge gap in the remote datastore code introduced in the
tinfoil2 rework - we weren't handling overrides at all, since these are
stored separately from the actual data in the DataSmart object. Thus,
when a datastore actually represents a remote datastore we need to go
back to that remote datastore to get the override data as well, so
introduce code to do that.

To avoid a second round-trip I had to modify the _findVar() function to
return the override data as well. This will increase the overhead a
little when that data is superfluous, but without making the function
even uglier I don't think there's a way to avoid that.
