RFR 8235413: com.sun.net.httpserver.BasicAuthenticator.charset is protected field

[Michael McMahon]

Hi,

Could I get the following trivial fix reviewed please. It is included in 
diff form below.

The problem was that a field "charset" was added as part of JDK-8199849, 
but it  was
made protected by mistake instead of private. The fix just makes it private.

There is no regression test for this issue, but the tests for 8199849 
all pass with the change

Thanks,

Michael
