Pull Request: 7013: AIX: InetAddress.getByName(addr) does not work as expected

[Michael Felt]

Hello all,

This is a test that fails in some environments - enough so that has been 
added to the ignore-list at AdoptOpenJDK (now Adoptium). And it will 
stay there until it gets fixed upstream.

I researched this and came up with differences that are behave 
differently depending on the environment, e.g., my server, and 
partitions hosted at IBM garage respond - at CLI -

```

aixtools at x064:[/data/prj/aixtools/tests]ping 0.0.0.0
PING 0.0.0.0: (0.0.0.0): 56 data bytes

--- 0.0.0.0 ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss
```

While at OSUOSL environment:
```

aixtools at nim.bak:[/home/aixtools]ping 0.0.0.0
PING 0.0.0.0: (0.0.0.0): 56 data bytes
64 bytes from 140.211.9.1: icmp_seq=0 ttl=255 time=0 ms
64 bytes from 140.211.9.1: icmp_seq=1 ttl=255 time=0 ms
64 bytes from 140.211.9.1: icmp_seq=2 ttl=255 time=0 ms

--- 0.0.0.0 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 0/0/0 ms
```

The patch is to make this test work in both environments - without any 
need to change the `java.net.InetAddress` or
`java.net.Inet6Address` definitions.

Regards,

Michael
