[oe] [meta-webserver][PATCHv3 1/2] nginx: optimize systemd unit file

[Gyorgy Szombathelyi]

- Call the nginx binary directly, no need to wrap the SysV init file.
- Create /var/log/nginx with tmpfiles, like volatiles without systemd.
- Run nginx with ${NGINX_USER} (user ${NGINX_USER} in nginx.conf)
