Fixing a race condition with virtual/kernel:do_deploy,
which needs to deploy the image before the IMAGE_CMD_sunxi-sdimg () code is being run
as part of image:do_rootfs, otherwise the following error would sometimes occur
when compiling with multiple threads (BB_NUMBER_THREADS=2):
"[..]/deploy/images/cubieboard2/uImage-cubieboard2.bin: No such file or directory"
Fixing this by using the kernel image in sysrootfs instead.
At the same time, also adding an explicit rootfs dependency on sunxi-board-fex:do_deploy because of
"${DEPLOY_DIR_IMAGE}/fex.bin", although this never seems to pose problems in practice.
There is a new recipe called sunxi-board-fex which cares about the
compiling of the FEX file for each machine. If there is a fex.bin file
available in the deploy directory and machine depends on it (see SD
image class) it will be added.
Only OLinuXino A10S uses it for now.
