Fix incorrect writing of grayscale JPEG images (bugs #41673, #44118, #42474)
* __magick_read__.cc: when writing grayscale images, we should create a
Magick::Image object of Magick::GrayscaleType type, then use Magick::Color
with only the red channel set (the other channels would be ignored). However,
this seems to not work for JPEG images which would then generate grayscale
images with one third of the intensity. This fixes it.
