Subject: [PATCH] dist/mkfile: add target for the aijuboard *.zynq.img

this generates a disk image (to be written to usb or
sdmmc card) containing 9fat partition with kernel and
a hjfs filesystem partition with the 9front distribution.

this could be easily extended to generate raspberry pi
images as well, but i have no hardware to test.
