py3k: handle file encoding and stream definition in builder

In Py3k, We can't do "data = open(path, 'U').read()" anymore since we need
to know the encoding to read the file (UnicodeError); instead we have
to first guess the encoding by reading the file as a byte stream.

We then define
+        node.file_encoding = encoding
+        node.file_stream = file_stream

to be used by the Pylint checkers
