[VS Addin] Disable PPAPI linking test except on VS2012 The pre-compiled libraries (specifically ppapi_cpp.lib) that we ship are only compiled with VS2012 so this test will fail on 2010 due to library incompatability. These tests used to pass with pepper_36 since at that point the SDK builders were still using 2010.
