The init.d script for php7-fastcgi no longer invokes php7-fastcgi with
the '-b' flag when 'port' does not appear in /etc/config/php7-fastcgi.
This causes php7-fastcgi to communicate using only a Unix socket.

This is a copy of the existing php5 stuff, adopted for PHP7.

Please not, that its not supported to install both php5
and php7 in parallel on the target.
