Fix Selector::try_clone

Calls fcntl F_DUPFD_CLOEXEC expects two arguments; the command
(F_DUPFD_CLOEXEC) and an argument for the command. In this case an lower
bound for the resulting file descriptor. Because we didn't provide a
value it would take whatever value was left in the register from
whatever code used it before the system call.

This caused Waker::new to fail, see issue
