[teststabilization] RFR: 8225578: Replace wildcard address with loopback or local host in tests - part 16

[Daniel Fuchs]

Hi,

Please find below a patch that fixes
java/net/Authenticator and java/net/CookieHandler to use
the loopback address - or the local host address if needed,
instead of the wildcard whenever that is possible:
