refactor(options): don't pass negative number to illegal_char() (#21999)

Browse Source 
This only changes the error messages for an unexpected Unicode char in
an option to show its first byte instead of some special keycode.

The second argument of vim_strchr() usually doesn't matter, but it may
be better to consistently cast to uint8_t.
