RFR: 8371722: java/net/httpclient/BufferSizePropertyClampTest.java should use Locale.ROOT [v2]

[Daniel Fuchs]

> The test verifies that the expected message is logged by the jdk.httpclient.HttpClient logger. However it fails when run in e.g. Polish Locale because it expects 16,384 and finds 16 384 (with a non breaking space).
> 
> The proposed change makes sure we use Locale.ROOT to format the message.
