image: add magic number option for append-uImage-fakehdr

'append-uImage-fakehdr' can now accept magic number as a second, optional
parameter (passed directly to 'mkimage' command with '-M' option). This
enables construction of proper Netgear-specific fake rootfs images
(required for flashing WNDR4300 for example).
