[2.16][PATCH] fetch2/git.py: fix update_mirror_links

From: Chen Qi <[email protected]>

We cannot assume ud has the same fetcher with origud. For example,
if we set map git:// to file:// in PREMIRRORS, ud is using local fetcher
and origud is using git fetcher. In such case, the ud does have the
'shallow' attribute. And we'll see the following error:

  Exception: AttributeError: 'FetchData' object has no attribute 'shallow'

Looking at the logic of this function, I think it's the origud's shallow
that should be checked. So the logic becomes: if origud is using shallow
and its full shallow tarball does not exist yet, symlink to ensure it
exists. This should make more sense.
