Add integration tests for Zephyr builder snippets support

This patch adds integration tests for Zephyr builder snippets support.
The tests are checking the following cases:
- Zephyr builder with one snippet
- Zephyr builder with two snippets
- Zephyr builder with snippet and shield
- Zephyr builder with no snippets
