remove HTTPS config from gitblit template

gitblit - remove the entire *:443 part from
the Apache config template, because it is actually
behind misc. varnish, so Apache should not handle
SSL anymore and only speak HTTP to misc. varnish

i didn't notice at first because the config is here
and wanted to make changes such as I092634cba9f8b

but when i saw in DNS it points ot misc-web-lb they seemed
useless and I abandoned in favor of this
