[OE-core][PATCH] qemuboot.bbclass: make sure runqemu boots bundled initramfs kernel image

[Jagadeesh Krishnanjanappa <workjagadeesh@gmail.com>]

The QB_DEFAULT_KERNEL is set to pick bundled initramfs kernel image
if the Linux kernel image is generated with INITRAMFS_IMAGE_BUNDLE="1".

This makes runqemu to automatically pick bundled initramfs kernel image
instead of explicitly mentioning bundled initramfs kernel image in
runqemu.
