It seems I met libcap errno bug again when using libcap-2.48-4.el8.x86_64.
But this time, errno is EINVAL if c program link with lcap.
Lastest upstream libcap doesn't have bug and it should be backport bug.
generic/478 will become not run because of this. To fix this that only
exists on some distributions, reset errno to zero.
