RFR: 8223696: java/net/httpclient/MaxStreams.java failed with didn't finish within the time-out [v2]

[Daniel Jeliński]

> The test was occasionally failing with TestNG timeout. When a TestNG test times out, TestNG interrupts the test thread, and starts another test case in a new thread. The timeout is invisible to JTReg, and the timeout failure handlers are not run.
> 
> This PR removes the TestNG timeout. It also removes `-ea -esa` from the test command line (the test does not use `assert`), and reduces the amount of synchronization objects used.
> 
> I verified that the timeouts are now handled by JTReg. The test still passes.
