qcam: dng_writer: Write EXIF IFD as custom directory
The EXIF IFD is incorrectly chained to IFD 0 in addition to being a
referenced as a sub IFD through the EXIFIFD tag. While the libtiff API
doesn't clearly document why this happens, inspection of the
TIFFWriteDirectory() source code show that the function treats the IFD
being written as containing an image, which isn't correct for the EXIF
IFD. Use TIFFWriteCustomDirectory() instead, which fixes the problem.
The resulting DNG file can now be opened with darktable in addition to
rawtherapee.
