graphics/darktable: Update to 4.4.1

Release notes:

• https://github.com/darktable-org/darktable/releases/tag/release-4.4.0
• https://github.com/darktable-org/darktable/releases/tag/release-4.4.1

Support for MIDI devices is currently turned off even though it probably
works just fine. The port already has many options that make it
complicated enough. If there is demand for MIDI devices, I will add the
option.
