init: Remove code to track line numbers in /etc/ttys.

Browse Source 
The tracking generated warnings when the line number of an existing tty in
/etc/ttys changed, which would corrupt utmp (as it was indexed by the line
number). With utmpx, the line number no longer matters, so the tracking is
no longer needed.
