Kernel+LibC: Default to 8-bit characters in TTY
Some ports (like `bc` with history enabled) sensibly set the termios
character size to 8 bits.
Previously, we left the character size value (given by the bitmask
CSIZE) as zero by default (meaning 5 bits per character), and returned
ENOTIMPL whenever someone modified it. This was dumb.
