#65618: mkvtoolnix: build fails when default variant 'qtgui' disabled: QT now
required across-the-board, even for non-GUI install, for v59.x and later

Component:  ports    |    Version:  2.7.2
 Keywords:           |       Port:  mkvtoolnix mkvtoolnix-devel
---------------------+-----------------------------------------
 Starting with release v59.x, this port now unconditionally depends on QT,
 utilizing the latter's MIME detection capabilities:

 system-changes

 In addition, starting with v58.x, QT 6 support was added. And since QT 6
 is prioritized over QT 5, the former will be opportunistically used if not
 explicitly disabled:

 https://gitlab.com/mbunkus/mkvtoolnix/-/blob/release-58.0.0/NEWS.md#build-
 system-changes

 All of which require port updates.

 Since `mkvtoolnix-devel` is based on the latest upstream release, the
 changes will be more straightforward there.

 However, since `mkvtoolnix` reverts to v53.x for older macOS releases,
 that will be a bit more involved.
