selftests/sched_ext: Fix flaky ddsp failure tests on busy systems
The ddsp_vtimelocal_fail and ddsp_bogus_dsq_fail tests skip calling
scx_bpf_dsq_insert_vtime() if scx_bpf_pick_idle_cpu() fails to find an idle
CPU (returns a negative error code). On loaded systems, this results in the
tests skipping the very assertions they are meant to verify.
Eliminate this flakiness by falling back to prev_cpu if no idle CPU is
found, ensuring the illegal dispatch operations are unconditionally
attempted and tested.
