Roman Lebedev 3384da9f27 [opt-viewer] Don't Decode HTML bytes for Python 2 
Summary:
D36624 added some python3 compatibility. But that fix has a problem..

With python2 (which is specified by `#!/usr/bin/env python2.7`), if the env variables do not specify the UTF8,
and the source file is UTF8 (contains non-ASCII symbols), then the `.decode('utf-8')` causes the following exception:
```
Reading YAML files...
Rendering HTML files...

    </tr>'''.format(**locals()), file=self.stream)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xf4' in position 47: ordinal not in range(128)
```
This is similar to https://bugs.llvm.org/show_bug.cgi?id=33548, which was fixed by https://reviews.llvm.org/D37661

Unlike that fix, here, *removing* `.decode('utf-8')` actually fixes it.

Since i assume that the original fix is needed, i simply made
that fix conditional, since for python2 it actually breaks things.
