selftests/sched_ext: Update scx_bpf_dsq_move_to_local() in kselftests

After commit 860683763ebf ("sched_ext: Add enq_flags to
scx_bpf_dsq_move_to_local()") some of the kselftests are failing to
build:

 exit.bpf.c:44:34: error: too few arguments provided to function-like macro invocation
    44 |         scx_bpf_dsq_move_to_local(DSQ_ID);

Update the kselftests adding the new argument to
scx_bpf_dsq_move_to_local().

Fixes: 860683763ebf ("sched_ext: Add enq_flags to scx_bpf_dsq_move_to_local()")
