hgweb: fix unbundle.
After the WSGI changes, even if a push over HTTP succeeds, apache
complains about "Premature end of script headers: hgwebdir.cgi" and
returns a "HTTP Error 500: Internal Server Error", making the local hg
abort.
The change to either of the files touched by this patch is enough to fix
this, but I think changing both is a more robust solution.
