push: pass --progress down to git-pack-objects

When pushing via builtin transports (like file://, git://), the
underlying transport helper (in this case, git-pack-objects) did not get
the --progress option, even if it was passed to git push.

Fix this, and update the tests to reflect this.

Note that according to the git-pack-objects documentation, we can safely
apply the usual --progress semantics for the transport commands like
clone and fetch (and for pushing over other smart transports).
