runqemu: Allow the user to specity no kernel or rootFS
In some cirsumstances the user doesn't want to supply a kernel, rootFS or DTB to QEMU. This will occur more now that QEMU supports loading images using a '-device loader' method. Allow users to specify 'none' for QB_DEFAULT_FSTYPE or QB_DEFAULT_KERNEL to avoid supplying these options to QEMU.
