kernel: cons: Fix newline caused by excessive '\b'

Before this commit, if you were to write out too many backspace
characters, it would result in an integer underflow for the
scr->curs_col and scr->ch_col state resulting in the console logic
assuming the cursor has gone too far off the screen which would cause
behavior similar to as if you wrote out a line-feed character.
