bitbake: fetch: support multiple mirror tarball filenames

Remove ud.mirrortarball in favor of ud.mirrortarballs. Each tarball will be
attempted, in order, and the first available will be used. This is needed for
git shallow mirror tarball support, as we want to be able to use either
a shallow or full mirror tarball.
