tests: output Docker container logs if test db freezes

When running the main package's integration test suite in CI (GitHub Actions),
sometimes tests fail at random due to the containerized database server
seemingly freezing up for ~50 seconds at a time. This has not been
reproducible outside of CI, and only ever seems to occur on the MariaDB
tests, typically the ones for either foreign keys or lower_case_table_names=1.

This commit adds a monitor goroutine which will dump out the last 100 lines of
the `docker logs` output (containing the database server error logs) whenever
the DB server appears frozen. If this is insufficient to diagnose the problem,
additional logging may be added in future commits.
