remote-curl: do not call fetch-pack when using gvfs-helper

When using the GVFS protocol, we should _never_ call "git fetch-pack"
to attempt downloading a pack-file via the regular Git protocol. It
appears that the mechanism that prevented this in the VFS for Git
world is due to the read-object hook populating the commits at the
new ref tips in a different way than the gvfs-helper does.

By acting as if the fetch-pack succeeds here in remote-curl, we
prevent a failed fetch.
