[PATCH v2 03/13] selftests/nolibc: waitpid_min: add waitid syscall support

[Zhangjin Wu]

waitpid() is based on sys_wait4().

When the first argument is INT_MIN, the wait4 syscall based sys_wait4()
return EFAULT by default, but the waitid syscall based sys_wait4()
return EINVAL in rv32 platform, let's support such case.
