        src/bin/sh: eval.c redir.c redir.h

Log Message:
Don't close-on-exec redirections created explicitly for the command being
ran; i.e. we want this to work:
        $ cat succ1
        #!/bin/sh
        ./succ2 6>out

        $ cat succ2
        #!/bin/sh
        echo succ2 >&6

        $ ./succ1

And this to fail:
        $ cat fail1
        #!/bin/sh
        exec 6> out
        echo "fail1" >&6
        ./fail2
        exec 6>&-

        $ cat fail2
        #!obj.amd64/sh
        echo "fail2" >&6

        $ ./fail1
        ./fail2: 6: Bad file descriptor

XXX: Do we want a -k (keep flag on exec to make redirections not close-on-exec?
