Log Message:
The web interface PHP uses the PHP sockets extension, at least from
share/zoneminder/htdocs/ajax/stream.php.

Because all the PHP extensions self-enable in this decade, there's no need
to configure php-sockets.  The same is also true of all the other
extensions, so just remove those unnecessary instructions from MESSAGE.

Bump PKGREVISION to 7 and bump year to 2022 (NZDT).
