RFR: 8371366: java/net/httpclient/whitebox/RawChannelTestDriver.java fails intermittently in jtreg timeout [v4]

[Daniel Fuchs]

> Nothing looks wrong with the test or the code. The failure happens rarely - probably when the machine is under load: this test tries to saturate the socket buffers and is resource consuming.
> 
> The proposed fix is just to double the jtreg timeout for this test from 120 to 240.
