tty/vt: consolemap: make parameters of inverse_translate() saner
- int use_unicode -> bool: it's used as bool at some places already, so
make it explicit.
- int glyph -> u16: every caller passes a u16 in. So make it explicit
too. And remove a negative check from inverse_translate() as it never
could be negative.
