    qemuboot.bbclass: don't fail on very first build
    
    During the very first build, the DEPLOY_DIR_IMAGE
    directory might not have been created yet, causing
    the creation of the qemuboot.conf config file to
    fail.
    
    This is because write_qemuboot_conf() runs at
    rootfs creation time, i.e. before deploy.
    
    So let's create the directory if necessary before
    trying to write the config file.
