LOG: [lldb] Change Python site-packages path (#207771)

On POSIX systems, traditionally the lldb Python module is in
lib/pythonx.x/site-packages. We only ever have 1 Python in a given
build, so we don't need to specify the version.

On Windows, we've always had the Python module in lib\site-packages.

Change the behavior on POSIX to match the Windows behavior, and put the
lldb Python module in lib/site-packages.
