Subject: ardour: add a `videoSupport` option

This adds a `bool` option that, when set to `true`, enables video
timeline support for the Ardour DAW. This is commonly useful for
soundtrack composition, sound design for film, etc.

When enabled, `videoSupport` ensures that both `harvid` and `xjadeo` are
available to the `ardour6` exe via the PATH. `harvid` decodes the video
stream in real-time to produce still images (I think for thumbnail
support for the timeline?). `xjadeo` acts as a video monitoring window
that whose playback position is synchronised to the Ardour playhead.

`videoSupport` remains disabled by default, preserving the original
behaviour.

Video support can be added to ardour in your system or home
configuration package list with:

```
(ardour.override { videoSupport = true; })
```
