Log Message:
Convert this package to the bsd.pkg.install.mk framework:
- Install configuration files under the examples hierarchy.
- Use CONF_FILES_PERMS to put the configuration files in place.
- Use SUPPORT_FILES_PERMS to put the empty log file in place.
- Use RCD_SCRIPTS to handle the rc.d script.

While here, add ICBD_OWNER to BUILD_DEFS and use ROOT_USER and ROOT_GROUP
where appropiate.

As a result, bump PKGREVISION to 1.
