[PATCH 7/7] fetch2: add symlink for shallow mirror tarballs

["Urs Fässler" <urs.fassler@bbv.ch>]

In the unpack step the shallow mirror tarball is not found when the
mirrored tarball is named differently than the original tarball. This
happens due to mirror rewrite rules. To solve the problem we add
symlinks for the differently named tarballs.
