hgweb: transition permissions hooks to modern request type (API)

We're trying to remove ``wsgirequest``. The permissions hooks don't
do anything they can't do with our new request type. So let's
pass that in.

This was the last use of ``wsgirequest`` in the wire protocol code!

.. api::

   hgweb.hgweb_mod.permhooks no longer take a ``wsgirequest`` instance
   as an argument.
