Git: Fix handling of symlinks in tree artifacts

The introduction of non-upwards symlinks as first-class objects
should have updated the handling of known git tree artifacts
containing symlinks. In particular, one should consider trees in
their entirety when uploading (irrespective of the ignore_special
flag), and git trees should only be reported as known only if
the ignore_special flag is set to false.
