Convert cursor bitmap to supported format
Fix issue with KStars cursor for wayland via backport 45ec1362
The 1-bit image formats QImage::Format_Mono and QImage::Format_MonoLSB used by cursor bitmaps don't have a corresponding wl_shm_format.
Therefore, convert to a supported image format as necessary to make such bitmap cursors work on Wayland as well.
