kexec-tools: Fix CRC calculation for padded uImage
Instead of calulating the CRC on the whole file just calculate the CRC on the actual uImage length as given by the uImage header. This fixes loading padded uImages, for example from a mtd partition. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com>
