bitbake: fetch2: Handle lockfiles for file:// urls redirected to mirrors
We recently dropped lockfiles for file:// urls which in itself makes sense. If a file url redirects to something like an http:// mirror, we'd have no lock taken for the original file and could race against others trying to download the file. We therefore need to ensure there is a lock taken in the mirror handling code. This adds code to take such a lock, assuming it isn't the same lock as the parent url.
