The F_DUPFD and its relative F_DUPFD_CLOEXEC both expect an int argument
as extra argument, being the minimal value for the new FD. This argument
must be within the accepted range (see ulimit -H -n).
This was detected in Ubuntu during testing against the latest glibc,
stracing resulted in:
107244 fcntl(1, F_DUPFD_CLOEXEC, 1847846346272) = -1 EINVAL (Invalid argument)
On the system in question (ppc64el machine running Ubuntu Questing), the
relevant limit is 524288.
For the fix we use 3 as a reasonable floor value, as in the first one
after stderr. It also happens to be the one used in revokefs/main.c.
