qemuboot: write the full kernel filename, not the link name
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.
