fix: make integration-tests.sh Mac friendly

network host on mac fails regularly due to how Docker runs on MacOS.

if on mac, keep network bridge mode.

before:

=== Starting Docker Container ===
Using image: localhost/distribution-ci-tests:dev
WARNING: Published ports are discarded when using host network mode
Waiting for Docker container to start...
❌ Docker container failed to start
Container logs:
INFO     2025-10-29 18:38:32,180 llama_stack.cli.stack.run:100 cli: Using run configuration:
         /workspace/src/llama_stack/distributions/ci-tests/run.yaml
... (stack starts but is not reachable on network)
after:

=== Starting Docker Container ===
Using image: localhost/distribution-ci-tests:dev
Using bridge networking with port mapping (non-Linux)
Waiting for Docker container to start...
✅ Docker container started successfully

=== Running Integration Tests ===
