runqemu: support booting poky-tiny image

Added support for booting poky-tiny images, which do not have block device support. Note to shut down a running poky-tiny image, you need to include the -f option to the poweroff command.

This fixes [YOCTO #2612].

you seem to be mixing poky distro with OE-Core here. As a whole the patch seems like adding support for ramfs based images. If you intend to just have images specific to poky then this patch belongs to OE-Core but if you generalize it enough that non

tiny users can also leverage this then it certainly is good for OE-Core.

you seem to be mixing poky distro with OE-Core here. As a whole the patch seems like adding support for ramfs based images. If you intend to just have images specific to poky then this patch belongs to [poky] but if you generalize it enough that non tiny users can also leverage this then it certainly is good for OE-Core.
