selftests/bpf: Fix resource leak in serial_test_wq on attach failure

When wq__attach() fails, serial_test_wq() returns early without calling
wq__destroy(), leaking the skeleton resources allocated by
wq__open_and_load(). This causes ASAN leak reports in selftests runs.

Fix this by jumping to a common clean_up label that calls wq__destroy()
on all exit paths after successful open_and_load.

Note that the early return after wq__open_and_load() failure is correct
and doesn't need fixing, since that function returns NULL on failure
(after internally cleaning up any partial allocations).
