graphics/darktable: Update to darktable 2.0.1

[dumbbell]

Summary

New upstream release.

In the OpenMP section, I added more comments to explain why we need each variable.

[kwm]

Since (I assume, no diff in the phab review ... yay) that both darktables have the same PORTNAME, you should add PKGNAMESUFFIX=2 so the name is unique.

Switch back to graphics/darktable, update to 2.0.rc3

[dumbbell]

The full patch (including added files) is available here:
https://people.freebsd.org/~dumbbell/darktable/ports-darktable-2.0.patch

This is still a release candidate, not the final release. I will only commit it once the release is here.

Update to darktable 2.0.0

[dumbbell]

2.0.0 is the final release, so this patch is ready to be committed.
