[oe] Git SRC_TARBALL_STASH filename

[Douglas Royds]

Working behind a firewall that doesn't allow Git access (except over 
http). I've set SRC_TARBALL_STASH so that we only have to download the 
appropriate source tarball (manually) once.

While building mtd-utils, BitBake is trying to fetch from the tarball stash:

    http://.../git_git.infradead.org.mtd-utils.git.tar.gz

Instead of:

    http://.../git_git.infradead.org.mtd-utils.git_ea429635388f7bb53f62c41ec3d5ccf5fa207370.tar.gz

The following patch appears to do the job, but I'm not confident this is 
the right fix. I notice that all the other fetchers use ud.localfile, 
which already has the correct filename.

Suggestions?
