Python 3 compatibility errors in third-party libraries

These changes fix Python 3 compatibility errors in third-party libraries
I'm not sure if these problems can be fixed this way.
But! (1) In deps/inspector_protocol no file roll.py
it looks like the repository v8 it shouldn't be, either.
(2) I have not found a separate repository for binutils.
