Link CEF files into webview sample build directory under Unix

Ensure that the sample can run using wxWebViewChromium backend out of
the box by setting things up so that it can find the CEF files. Note
that we use symlinks instead of actually copying these files, to avoid
wasting so much disk space (CEF libraries take more than 1GiB).
