Skip Sury extensions not packaged separately per PHP minor

PHP 8.5 made opcache a core, always-available extension; Sury ships it
inside php8.5-common rather than as php8.5-opcache. The previous flat
package list aborted the build (`Unable to locate package
php8.5-opcache`).

Filter the extension set through `apt-cache show` before apt-get, log
what got skipped, install the rest. Same pattern in pvm's `install`
subcommand so adding versions later doesn't regress.

Also add apcu to the default extension set (Symfony cache adapters).
