The kernel configuration of the beaglebone-yocto MACHINE supports booting
on real hardware as well as in Qemu. Add an oe-selftest which tests that
booting in Qemu is possible even when the kernel is a FIT image kernel
with a RAM disk.
Since Qemu does not support FIT images, Qemu boots the zImage in direct
kernel mode. This works with or without initramfs.
