Add extra directory to look for vcpkg in GitHub Actions runner. (#1779)

Summary:
Pull Request resolved: #1779

Adding extra directory to look for vcpkg in GitHub Actions runner.
In initial tests the `C:/vcpkg` has been used but recently a CI test failed because `D:/a/beanmachine/beanmachine/vcpkg` was used instead, so we are adding it to the search options.
Also fixing local directory search option.
