[Test] Use locally built Rspamd in integration tests instead of prebuilt image

Changed integration test setup to build and test the current code
instead of using the asan-nightly Docker image:

- Modified docker-compose.yml to use local build via Dockerfile.local
- Created Dockerfile.local with ASAN-enabled Ubuntu 24.04 base
- Removed redundant docker-compose modification step from workflow
- Added .dockerignore to exclude test data from build context

This ensures integration tests actually test the code changes being
made in pull requests, not an outdated nightly build.
