    scripts: Fix git-checkout.sh to work with branches other than master
    
    Xen uses master for QEMU_UPSTREAM_REVISION, and has done for other trees too
    in the path.  Apparently we've never specified a different branch, because 
the
    git-clone rune only pulls in the master branch; it does not pull in 
diverging
    branches.  Fix this by stating which branch/tag is wanted.
    
    $TAG is really a committish, and git-clone's -b/--branch takes a committish
    too.
