4fd4aa40ee switch to C.UTF-8 locale 
en_US.UTF-8 still needs to be generated for now since the PostgreSQL
databases and potentially other applications will still be using it.

36423fb2bc auto-restart nginx if master process is killed 
nginx handles restarting workers automatically but the master process
is typically killed by the OOM killer too.

320ad2e3a8 replace tmpfiles.d with RuntimeDirectory for nginx 
This is much more robust because nginx will fail to start after being
killed or crashing due to only removing old Unix domain sockets when it
stops cleanly. It ends up owned by root:root instead of root:http which
is fine because only the master process opens it.
