tools: Add mkimage-rpi3 to build images for raspberry Pi 3

Browse Source 
The package contains u-boot and the RPi firmware blobs. It expects
a tar ball of the root filesystem (including kernel and dtbs) on stdin
and produces a compressed tar ball on stdout with the files to copy to
a FAT32 formatted SD card.
