RFR: 8276848: sun.net.httpserver.simpleserver.CommandLinePositiveTest: test does not specify port [v2]

[Julia Boes]

> This change corrects the server configuration in `testBindAllInterfaces` to specify the port. Additionally, a manual test is added for the case where the port is not specified and the server uses the default port 8000, which might already be in use by another test. To avoid this scenario and the resulting BindException, the test is made manual.
