sched_ext: initialize kit->cursor.flags
struct bpf_iter_scx_dsq *it maybe not initialized.
If we didn't call scx_bpf_dsq_move_set_vtime and scx_bpf_dsq_move_set_slice
before scx_bpf_dsq_move, it would cause unexpected behaviors:
1. Assign a huge slice into p->scx.slice
2. Assign a invalid vtime into p->scx.dsq_vtime
