[jdk17] RFR: 8269772: [macos-aarch64] test compilation failed with "SocketException: No buffer space available"

[Daniel Fuchs]

Please find here a trivial fix for:

8269772: [macos-aarch64] test compilation failed with "SocketException: No buffer space available"

Running several of the websocket tests concurrently on some of the CI machines is causing resource exhaustion, because resources are only freed after the TIMED_WAIT delay has expired once the tests have finished.
The proposed solution is to run these tests in exclusive dir mode.
