And if you think about checking PIDFD_INFO_EXIT in the test setup() that
may be doable. But there is no need for configure checks in that case,
we just use PIDFD_INFO_EXIT fallback definition from the lapi headers.

I suppose adding a check for support that would be called if kernel
version is older than 6.15 would work as well.
