* when searching for qemuboot.conf
* don't assume that IMAGE_LINK_NAME is always
<rootfs>-<machine> (with <rootfs>-<machine>.qemuboot.conf)
* runqemu: use IMAGE_LINK_NAME set by testimage.bbclass or query with bitbake -e
* testimage.bbclass was setting DEPLOY_DIR which I don't see used
anywhere else, so I assume it was supposed to be DEPLOY_DIR_IMAGE as mentioned
in corresponding runqemu code, do the same with IMAGE_LINK_NAME variable
* add virtual/kernel as bitbake -e target in run_bitbake_env to make
sure IMAGE_LINK_NAME is defined (kernel-artifact-names.bbclass inherits
image-artifact-names.bbclass as well)
* improve .qemuboot.conf search
1st search for file matching the rootfs and only when not found
try again with .rootfs suffix removed
