Webserver user/group

[Frédéric Fauberteau <triaxx%NetBSD.org@localhost>]

I mainly run www/nginx as webserver. I also run www/php-fpm that uses an unprivileged user FPM_USER?= ${APACHE_USER}. In my mk.conf, I have APACHE_USER= nginx. I would prefer to have web services' unprivileged users depending on a generic WWW_USER that could be configured according to the webserver actually running.

Do you have objection concerning the following patch:
