Yonghong Song ec9230b18b selftests/bpf: Fix a selftest compilation error with CONFIG_SMP=n
Kernel test robot reported bpf selftest build failure when CONFIG_SMP
is not set. The error message looks below:

  >> progs/rcu_read_lock.c:256:34: error: no member named 'last_wakee' in 'struct task_struct'
             last_wakee = task->real_parent->last_wakee;
                          ~~~~~~~~~~~~~~~~~  ^
     1 error generated.

When CONFIG_SMP is not set, the field 'last_wakee' is not available in struct
'task_struct'. Hence the above compilation failure. To fix the issue, let us
choose another field 'group_leader' which is available regardless of
CONFIG_SMP set or not.

Fixes: fe147956fc ("bpf/selftests: Add selftests for new task kfuncs")
Fixes: 48671232fc ("selftests/bpf: Add tests for bpf_rcu_read_lock()")
