Matthew Flatt dbba480ad3 raco pkg: adjust the way a local clone is made for updates
When a clone-linked package is updated, a temporary extra clone
is created to checkout the target commit for dependency and conflict
checking.

The current strategy for cloning a repository doesn't work for some
Git versions. The problem is that the target commit is unlikely to
be reachable from any current branch or tag, and so it might not
get carried along in the clone (depending on the Git version).
Originally, a `git fetch <commit>` compensated for that problem,
but fetching a particular commit doesn't work for all Git versions,
either.

The new strategy is to clone with `--shared`, which ensures that
just-fetched commits are all available in the temporary clone (and
it also avoids a little unnecessary copying work).
