Run patchbot on all tickets, including those with package changes

[mkoeppe]

Skipping tickets that involve package changes is an outdated, unnecessary restriction.
Just use configure --enable-download-from-upstream-url.

This behaviour is here in patchbot.py :

                is_spkg = branch_updates_some_package() or ticket['spkgs']
                if is_spkg:
                    # ------------- treatment of spkgs -------------
                    state = 'spkg'
                    print("Ticket updates some package, hence not tested.")
                    self.to_skip[ticket['id']] = time.time() + 240 * 60 * 60

                if not is_spkg:

One can easily desactivate this check. Somebody needs to run a modified patchbot on a package-upgrade ticket to check that it works.
