Make sure we don't check in the wrong things

Since we shouldn't be dependent on the tests or assets we copy over from Android we should also make sure not to check them in since they will just be overwritten on the next build anyway.

Also the couchbaselitetest directory is an artifact created by testing and shouldn't be checked in either.
