main/fcgiwrap: fix init.d script and claim maintainership

- split openrc subpackage
- use /run instead of /var/run for socket dir
- remove use of pidfile. It seems that the first process will not clean
  up the childen. Let openrc kill all children by not specify pidfile
- fix permission of unix socket path. it needs to be writable by
  www-data group.
- clean up unix socket after stop
- make it possible to set number of preforks via 'nproc' in
  /etc/conf.d/fcgiwrap. default to number of cpus on system.
- allow set tcp socket via /etc/conf.d/fcgiwrap
- provide example /etc/conf.d/fcgiwrap
