Set BUNDLE_WITHOUT from init.rb
Set BUNDLE_WITHOUT from init.rb

init.rb expects $servelet_container to be set. Luckily, it uses ||= to
set those env variables. To move forward, I'm pre-setting them so that
$servelet_container isn't used (since it is not set), but this
could/should be done much nicer.
