tty/vt: Remove printable variable

Browse source 
Every since the 0.99.7A release when console_register() was introduced
it's become impossible to call vt_console_print (called
console_print() back then still) directly. Which means the
initialization issue this variable protected against is no more.

Give it a send off with style and let it rest in peace.
