largefiles: improve repo wrapping detection

Before this patch, repo wrapping detection in "reposetup()" of
largefiles can detect only limited repo wrapping: replacing target
functions by another one named as "wrap".

So, it can't detect repo wrapping even in recommended style: replacing
"__class__" of repo by derived class.

This patch can detect repo wrapping in both styles below:

  - replacing "__class__" of repo by derived class (recommended style):

        class derived(repo.__class__):
            def push(self, *args, **kwargs):
                return super(derived, self).push(*args, **kwargs)
        repo.__class__ = derived

  - replacing function of repo by another one (not recommended style):

        orgpush = repo.push
        def push(*args, **kwargs):
            return orgpush(*args, **kwargs)
        repo.push = push
