GIT-VERSION-GEN: Recognize git version in gitweb snapshots.

gitweb prepends the repo name and the git version number to all paths
of the snapshot tarballs (example: paraslash-32a81d7/). This commit
teaches GIT-VERSION-GEN to make use of this information. The patched
script reports the git version thusly encoded in the current directory,
rather than resort to "unnamed_version" as before.
