Use `fcntl(fd, F_GETFD)` to detect if standard streams are open
In the previous implementation, if the standard streams were open, but the RLIMIT_NOFILE value was below three, the poll would fail with EINVAL: > ERRORS: EINVAL The nfds value exceeds the RLIMIT_NOFILE value. Switch to the existing fcntl based implementation to avoid the issue.
