runqemu: improve finding of rootfs, kernel and dtb
* 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.
