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.
