    image.bbclass: Correct chaining compression support
    
    When chaining of compression/conversion types was added, we had a new
    way to handle doing things like "ext4.bz2.sha256sum" or
    "ext2.gz.u-boot".  However, because the U-Boot image class isn't
    included normally, it wasn't properly converted at the time.  After the
    support was added the "clean" argument that the .u-boot code uses no
    longer functions.  The fix for this inadvertently broke chaining
    compression/conversion.  First, correct the u-boot conversion code.
