fix ci : check libFoundation on HelloWorld example (#593)

Fix errors in the CI
The script that checks the presence of `libFoundation` in the binary
started to fail.
I can't think about a recent change that would cause this.

This PR change the test script to use the `HelloWorld` example instead
of `APIGAtewayV2`
