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.
