    bitbake: fetch/gitannex: add support for shallow mirror tarballs
    
    When we're building from a shallow mirror tarball, we don't want to do
    anything with ud.clonedir, as it's not being used when we unpack. As such,
    disable updating annex in that case. Also include annex files in the shallow
    tarball.
