RFR: 8318442: java/net/httpclient/ManyRequests2.java fails intermittently on Linux [v2]

[Matthias Baesken]

> On Linux ppc64le test machines (RHEL8.5, Ubuntu 22.04) we see intermittent failures of java/net/httpclient/ManyRequests2.java .
> We mostly run fastdebug binaries for our tests on  Linux ppc64le; unfortunately those are very slow and the current timeouts of this test are not sufficient on this platform.
> With these increased values the test was stable also on Linux ppc64le over the last few months .
