#11560: let proxy models multiple-inherit from the same concrete base model

Currently proxy models are required to have a single concrete base model
class. Unfortunately this prevents me from combining several proxy
subclasses of the same model. In my particular use case, I have two
different apps that provide two different proxies of the standard User
model. To successfully use both apps I need to create another subclass
that combines the two, e.g:
{{{
class MyUser(App1User,App2User):
class Meta:
proxy = True
}}}
This gives a TypeError: "Proxy model 'MyUser' has more than one non-
abstract model base class". But since App1User and App2User proxy the
same underlying model, there's no ambiguity introduced by this multiple
inheritance and I think it should be permitted.
Attached is a simple patch to make this work, by permitting additional
concrete base classes if they are identical to the one that was already
found.
