tty: fix 'statuslines' off by 1 error

Browse Source 
With CLIPPING disabled you should need a terminal or window with at
least 25 lines to change the 'statuslines' option from 2 to 3, but
it was being allowed on tty when there were only 24 lines available.

I think the other interfaces always have clipping capability enabled
so aren't affected.

Not many level maps extend to the bottom row (line 22 for a 1-based
count) so it wasn't likely to be noticed during play.  That points
that maps which don't use all rows and/or all columns could get by
without clipping by adjusting their position.  However, implementing
adaptive clipping is not something that I'm going to try to tackle.
