[RFR] [8u242] [2/2] 8132111: Do not request for addresses for forwarded TGT

[Andrew John Hughes]

Bug: https://bugs.openjdk.java.net/browse/JDK-8132111
Webrev: https://cr.openjdk.java.net/~andrew/openjdk8/8132111/webrev.01

And here's the second part. Key bit is the removal of sAddrs, which
avoids a crash when new HostAddresses(server) is called to set it.

Only difference in the backport is the KrbTgsReq constructor in KrbCred,
which already has an extra argument in 8u, thanks to the backport of
JDK-8227437.

Thanks,
