From: Joshua Lock <joshua.g.l...@intel.com>

KERNEL_IMAGETYPE gives the filename of a symlink to the kernel,
which may not be available i.e. if the user downloads some build
artefacts to run on a local machine. It's also possible that the
link will point to a newer kernel than was intended for use with
the rootfs in the qemuboot.conf.

It's much more reliable to read the name of the file
KERNEL_IMAGETYPE is linking to and assign the full filename to
QB_DEFAULT_KERNEL.
