Make tests/integration/Dockerfile.test more secure

[manuelbuil]

Proposed Changes

Make the Dockerfile.test more secure by:

• Remove the "dep" installation because it is not needed and "curl" either
• Adding "--no-install-recommends" to reduce unnecessary packages.
• Removed apt metadata after install with rm -rf /var/lib/apt/lists/*.
• Pin the ginkgo and gomega version when installing it via "go install"
