Extended Description

We sometimes test executables that link against shared libraries. In this case the executable and shared libraries are built separately, and not always in the same location. The executable needs to be able to find the shared library at runtime. This needs to be fixed by setting an appropriate PlatformContext in lldbtest.py for Windows that adds the shared library folder to PATH, rather than setting it to null.

This does not appear to be an issue anymore and it looks like this test now passes with no problems.
