src/dfa/closure_posix.cc: fix signed shift overflow

signed shift overflow is not defined by C standard.
clang++ -fsanitize=undefined detects it as:

```
src/dfa/closure_posix.cc:207:32: runtime error: left shift of negative value -1
```

This change wraps bit shift arithmetics into unsigned types.
