Make MySQL wait strategy less flaky

Removed the `wait.ForExposedPort()` override from test files. The tests
will now use the MySQL module's default wait strategy
(`wait.ForLog("port: 3306  MySQL Community Server")`), which properly
waits for MySQL to be ready to accept connections. Otherwise the port
may be exposed, but MySQL is still initializing and not ready to accept
connections.
