${PKG_SYSCONFDIR} to not be automatically creates/refcounted by the
+DIRS script for packages that only set CONF_FILES_PERMS and not
CONF_FILES or PKG_SYSCONFSUBDIR, e.g. security/sudo. This caused
problems when PKG_SYSCONFBASE was set to a non-default directory that
didn't pre-exist, e.g. PKG_SYSCONFBASE=/etc/pkg. Problem noted by
<jmmv>.
