Bind php-fpm to all interfaces by default

Upstream php:*-fpm moved the listen directive from zz-docker.conf into docker.conf, so our www.conf (written by entrypoint) is now the last file to set listen and its 127.0.0.1:9000 value takes effect. That breaks web->php connectivity in multi-container setups. Default to listen = 9000 so other containers can reach php-fpm; users can still lock it down via PHP_FPM_OVERRIDE.
