Fix `IO#readchar` to return broken UTF-8 rather than `EOF` error.
The behavior is different from CRuby, but we believe this is a right
behavior for mruby, which only supports either ASCII or UTF-8
exclusively; fix #4983, ref #4982
```
$ printf '\xe3\x81' | ruby -e 'p STDIN.readchar'
"\xE3\x81"
```
```
$ printf '\xe3\x81' | mruby -e 'p STDIN.readchar'
"\xE3"
```
