Tor: remove support for the pre-0.3.5 directory structure
Our git scripts and some of our test scripts still support Tor's pre-0.3.5 directory structure.
Now that 0.2.9 is unsupported, we can remove this code.
We should be able to find it by grepping for "0.2.9", "029", "src/or", "src/common", "0.3.5", or "035".
