[Java] Ensure Flight with native Netty transport is actually being tested

There's only one test that exercises the domain socket path and it appears it's getting skipped on CI
```

[INFO] Running org.apache.arrow.flight.TestServerOptions
Warning:  Tests run: 5, Failures: 0, Errors: 0, Skipped: 1, Time elapsed: 0.024 s - in org.apache.arrow.flight.TestServerOptions
```
We should make sure this test works and figure out whatever Maven magic we need to get the right dependencies on the right platforms

Start by running org.apache.arrow.flight.TestServerOptions and checking why the domain socket test is skipped in CI. Inspect the Maven configuration and platform-specific dependencies for native Netty transport. Done means the test executes successfully, rather than being skipped, on the applicable CI platforms.
