Fix support for subdirectory installs with WSGI.

Subdirectory installs were broken out of the box. The generated
WSGIScriptAlias wasn't handling the path passed in. This now works out
of the box for both subdir installs and standard installs.
Performed new site installs for both "/" and "/rb/". In both cases, I
had a working install, whereas the latter failed before.
