Title: guard against server only options being configured at location scope

guard against server only options being configured at location scope
this introduces a duplicated list of server-level-only options from mod_instaweb.cc,
which is a short term solution and should be removed later on

this should fix https://github.com/pagespeed/ngx_pagespeed/issues/99
