2.1 regression: missing JACK library version check

It seems the new JACK audio output depends on relatively recent client library features. A corresponding check needs to be added to configure.ac

jack: check for jack >= 1.9.7 or jack >= 0.120.1 (fixes [#8493](https://code.videolan.org/videolan/vlc/-/issues/8493))

These are the versions of JACK and JACK2 which introduced the
latency API.
Error out if JACK is not installed and "--enable-jack" was used.
