Wrong group owner of FPM Socket on Centos with NGINX

short description

ISPConfig creates on CentOS (tested on 6 and 7 latest) systems with NGINX 1.10.2 running, for some reason fpm confs with the apache group instead of clientX which leads to unaccessible socket files and the website can't be accessed anymore.

Example:
0 srw-rw---- 1 web9 apache 0 17. Okt 15:03 /var/lib/php5-fpm/web9.sock

correct behaviour

After reverting this commit: 0dfb2d97 the fpm conf is being created correctly with the correct group.
