Implement dup3

[robinyuan1002]

When I was testing uniq in coreutil, uniq tried to call dup3, but we don't have dup3. The solution I currently use is to call dup2 (uniq can run), but this gives up the functionality of the dup3 flags.

From what I see, this seems trivial to implement. A PR would be welcome.
