The host tool package qemu is build for the target x86. The installed tool
qemu-img is needed to build vdi or vmdk images. In the image Makefile we
use however the host installed qemu-img command and not the tool from the
buildsystem. This commit force to use the already build qemu-img command
from the openwrt toolchain.
