Fix the failing windows clang unit tests. NFC

[sgundapa]

Summary

Some tests are missing the {{(.exe)?}} suffix on the exectables
which the FileCheck is grepping for. This will ensure, the lit tests
are clean on windows

I can not seem to possibly find a windows community bot. It would be nice if some one can point me to that.
