[Driver] Test for correct '--version' suggestion
Summary:
The `llvm::OptTable::findNearest` bug fixed in
https://reviews.llvm.org/D41873 manifested itself as the following
erroneous message when invoking Clang:
```
clang -version
clang-6.0: error: unknown argument '-version', did you mean 'version'?
```
Add a test to catch any future regressions to the now correct behavior,
which asks "did you mean '--version'?".
Test Plan: `check-clang`
Reviewers: v.g.vassilev, teemperor, ruiu, jroelofs, yamaguchi
