In the Blt service of the EFI_GRAPHICS_OUTPUT_PROTOCOL the parameter delta
is measured in bytes and not in pixels.
The coding only supports delta being a multiple of four. The UEFI specification does not explicitly require this but as pixels have a size of four bytes we should be able to assume four byte alignment.
The corresponding unit test is corrected, too. It can be launched with
setenv efi_selftest block image transfer bootefi selftest

I can verify that this makes grub GOP work again :)
Kernelflinger works too.
