selftests/bpf: skip the timer_lockup test for single-CPU nodes
The timer_lockup test needs 2 CPUs to work, on single-CPU nodes it fails
to set thread affinity to CPU 1 since it doesn't exist:
# ./test_progs -t timer_lockup
test_timer_lockup:PASS:timer_lockup__open_and_load 0 nsec
test_timer_lockup:PASS:pthread_create thread1 0 nsec
test_timer_lockup:PASS:pthread_create thread2 0 nsec
timer_lockup_thread:PASS:cpu affinity 0 nsec
timer_lockup_thread:FAIL:cpu affinity unexpected error: 22 (errno 0)
test_timer_lockup:PASS: 0 nsec
#406 timer_lockup:FAIL
Skip the test if only 1 CPU is available.
