community/millipixels: Workaround libtiff 4.5.1
This backports a fix from https://source.puri.sm/Librem5/millipixels/-/merge_requests/105
to address: https://source.puri.sm/Librem5/millipixels/-/issues/87
This fixes the issue where the saved image is black and white and 3 small copies instead of the correct image.
This fix is already applied to megapixels, this just applies the same fix to millipixels.
