First, rename $TAG to $COMMITTISH. We already pass tags, branches (well, only master) and full SHAs into this script. 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 performing an explicit fetch of the $COMMITTISH, then checking out the dummy branch from the FETCH_HEAD.
