runqemu: improve finding of rootfs, kernel and dtbrbt/rq
* Search rootfs in the following order: - IMAGE_NAME*.FSTYPE - IMAGE_LINK_NAME*.FSTYPE * Search kernel in the following order: - QB_DEFAULT_KERNEL - KERNEL_IMAGETYPE - KERNEL_IMAGETYPE* * Search dtb in the following order: - QB_DTB - QB_DTB* - *.dtb * Fix DTB, it should only work with "-kernel" option. [YOCTO #10265] Signed-off-by: Robert Yang <liezhi.yang@windriver.com>
