Remove "failed to querty stty columns" spam. Fixes BUKKIT-1669.

When trying to execute stty to get terminal properties an
InterruptedException can be triggered even though we've read all of the
output from stty that we need. Instead of printing a warning and returning
-1 in this case try to parse what data we do have and reset the cache timer.
May also address BUKKIT-1627 and BUKKIT-1686.
