Fix apt-cacher-ng configuration for build container

- Use --network host for apt-cacher-ng to ensure accessibility
- Try multiple connection methods (host.docker.internal, 172.17.0.1, host-gateway)
- Use correct port 3142 instead of 3143
- Add proper cleanup and testing of apt-cacher-ng service
- This should resolve udev dependency installation issues

The build container was unable to reach apt-cacher-ng, causing
udev package installation to fail and meson configuration to fail.
