nixos/atftpd: various improvements 

* Add extraOptions option, to pass arbitrary command line options to
  atftp. Especially useful to specify which address to bind to
  (--bind-addres ...).
* Improve descriptions (fix a typo, document default bind address,
  don't repeat service name in systemd description + capitalize)
* Change default server directory from /var/empty to /srv/tftp, and
  change types.str to types.path.
