Subject: test/lit.cfg: Add PATHEXT to 'substitution', to recognize tools on
 Windows hosts. Thanks to Danil Malyshev!

Some tests on Windows use the "not" utility and fail with an error "program not executable". The reason for this error is that the name of the executable file sended to the "not" without the extension.
