hgweb: drop "parity" from webutil.diffs arguments

This function yields "diffblock" templates which do not make use of "parity".
In fact, maybe this template *should* make use of parity stripes as it would
make /rev views more readable with the diff involves several files?

From mercurial/templates/spartan/map:
diffblock = '<pre class="parity{parity}">{lines}</pre>'

So I don't think this is unused?

You're right. I will change this in a V4 so that "parity" is computed
inside the function.
