vt: expose system-wide UTF-8 default setting via sysfs
Create a variable, default_utf8, that defines the system-wide default UTF-8 setting. This variable can be altered via sysfs. If the variable is properly set, this should mimimize breakage of UTF-8 encoded consoles when doing a reset or echo -e '\033c' and of newly opened/allocated consoles. This is based from patches by Jan Engelhardt and Paul LeoNerd Evans.
