Add a slightly redundant arg to finishdup that's the struct file *

present on the 'old' descriptor. It's not really necessary because
we can easily find it with 'fp = p->p_fd->fd_ofiles[old];', but this
allows us to require that the fp is FREFed without violating all rules
of good taste and all callers have to do fd_getfile on it anyway (to
detect larval and closing files.

FREF the fp in all callers.
