hgweb: fix the MRO in Python 3
object should appear at the end, otherwise it tries to pre-empt the other
new-style classes in the MRO, resulting in an unresolvable MRO in Py3. We still
need to include object because otherwise in 2.7 we end up with an old-style
class if threading is not supported, new-style if it is.
