    libvirt: Use os_command_line when kernel_id is set

    Patch Iad53c687053bdb5469baad4331ea55f428c170b0 breaks libvirt with
    "-append only allowed with -kernel option" when using images without an
    explicit boot kernel set because the -kernel option (kernel_id in nova)
    isn't supplied for those image types.

    This patch reads the os_command_line property from the image metadata
    only when using images with an explicit boot kernel set and ignores it
    otherwise.
