Fix up some SSL configuration, per issue #49484. IE6 had a hotfix released

for this problem quite a while back (see kb 921090), so restrict the
modified behavior to the old/unsupported browsers.

* docs/conf/extra/http-ssl.conf.in:
  (): tighten up the regex to only select old MSIE browsers for the
    downgrade in http behavior. this allows IE6 to run much faster.
