RFR: JDK-8226420: sun/tools/jstatd tests failed with Port already in use

Fri Sep 1 23:00:55 UTC 2023

Logic to detect "port in use" case and retry was implemented in the test by JDK-8240711.
Infra issue with some test host when system software listened on port 1099 was resolved long time ago.

So JDK-8226420 can be closed as a duplicate, but problemlist entries for sun/tools/jstatd tests mention 8226420.
The fix removes 8226420 from problemlist (the tests remain problemlisted due other issues).
