Build NGINX from source with nginx.ng state with support for passing
compile time flags necessary for installing modules such as more headers
by the openresty project.
this is needed on archlinux where the pid file is set by systemd
not the nginx.conf file.
In the pillar file you just add
pid:
an value of 'None' and no pid entry in nginx.conf.
this now works with every None value set in the pillar file
