[Python] Fix issue configuring sys.path during startup.

Previously, users on Windows had to manually specify PYTHONPATH
to point to the site-packages directory before running LLDB.
The reason for this was because sys.path was being initialized
with a path containing unescaped backslashes, causing escape
sequences to end up in the paths.
