[bug#30771] Add kdenlive

[Mark Meyer <mark@ofosos.org>]

[-- Attachment #1: Type: text/plain, Size: 360 bytes --]

Moin,
This adds kdenlive. Since the upstream project has no links to tarballs, we take the current release from Git. Note, you will need an updated MLT. It is recommended that you install `breeze-icons' in addition to this, but kdenlive without them being present.

See: guix-patches 30770 for the mlt changes.

Cheers, Mark
