[POWERPC] bootwrapper: Make compression of the kernel image optional.
The --no-gzip option can be passed to the wrapper so that the kernel image is included uncompressed into the zImage. This is intended for bootloaders where the zImage itself can be compressed, or where boot time is considered more important than kernel image size.
