runqemu: fix ROOTFS for vmdk

* Make it can boot scsi and virtio block drive such as root=/dev/sdX and
  /dev/vdX.

* Drop VM from help info, id doesn't work, and the script can check
  whether it is a vm disk or not.

* Make it can be run by:
  $ runqemu tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.vmdk
  or:
  $ runqemu qemux86-64 vmdk
