wasmtime-c-api: Remove duplicate tests of examples
The canonical examples tests will be the examples run via `cargo run -p run-examples` from now on. Those tests have two advantages over the ones being deleted: 1. They will automatically pick up new examples and run/test them. 2. They support all of Linux, MacOS, and Windows, while the tests being deleted are Linux only.
