localrepo: pass ui to newreporequirements() (API)

newreporequirements() is called as part of creating a new repository.
It doesn't make much sense for it to receive a repo instance as part
of determining what requirements for new repos should be.

.. api::

   localrepo.newreporequirements() receives a ui instead of a repo
