    qemuboot.bbclass: do not hook into do_rootfs
    
    Writing qemuboot.conf in write_qemuboot_conf() does not modify the
    rootfs and thus conceptually shouldn't be executed as part of rootfs
    creation.
    
    Running it as separate task is cleaner and fixes the problem of
    missing qemuboot.conf files for meta-swupd virtual images; those
    images replace do_rootfs and ROOTFS_POSTPROCESS_COMMANDs don't run at
    all.
    
    The task gets added such that it runs roughly at the same time as
    before. Probably it doesn't actually need to depend on do_rootfs, but
    this way we don't write a useless qemuboot.conf in cases where
    do_rootfs fails.
