lfs: convert to using exthelper to wrap functions

I'm not 100% sure that upgraderequirements() can be double annotated safely, but
it seems OK based on printing the address of the function being wrapped.

One thing I've noticed is that @eh.reposetup doesn't do the usual check to
ensure that it's a local repo.  Should that be baked into @eh.reposetup()
somehow, possibly with a non-default option to skip the check?  It seems like a
gaping hole if every function that gets registered needs to add this check.

__path__ = pkgutil.extend_path(__path__, __name__)
