    gd: fix compile error caused by -Werror=maybe-uninitialized
    
    When enable DEBUG_BUILD, gd compile failed with error:
    
    | ../../git/src/gd_tiff.c:961:64: error: 'image_type' may be used uninitialized in this function [-Werror=maybe-uninitialized]
    |           (image_type == GD_PALETTE || image_type == GD_INDEXED || image_type == GD_GRAY)) {
    |           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~
    
    actually, this warning is misinformation, we can see the logic from:
    https://github.com/libgd/libgd/blob/master/src/gd_tiff.c
    image_type will be assigned no matter force_rgba is TRUE/FALSE.
