    rc.d/serial: Kill dtrwait
    
    The dtrwait wait functionality was dropped in the TTY MPSAFE rewrite for
    FreeBSD 8. Remove referneces to it here. Also, the sysctl was renamed
    for drainwait, so use the new name. Given the 16 years between this
    event and somebody noticing, I strongly suspect this file can just be
    removed.
