TestHumongousCodeCacheRoots should be excluded on aix

[pmikova]

Hi,

during AQA triage, I found a failing test TestHumongousCodeCacheRoots
(for more context see)
#5233 (comment)

Looks like the test is looking for a missing VM opt, which is not present on this architecture.

[2024-04-17T12:42:33.421Z] STDERR:
[2024-04-17T12:42:33.421Z]  stdout: [];
[2024-04-17T12:42:33.421Z]  stderr: [Unrecognized option: -client
[2024-04-17T12:42:33.421Z] Error: Could not create the Java Virtual Machine.
[2024-04-17T12:42:33.421Z] Error: A fatal exception has occurred. Program will exit.
[2024-04-17T12:42:33.421Z] ] 

The test should have been excluded as a part of:
#2800

Specifically:
#2818

Thank you!

Test case code is here https://github.com/adoptium/jdk8u/blob/master/hotspot/test/gc/g1/TestHumongousCodeCacheRoots.java

Test runs in -server and -client mode. We can check if it ran and passed in -server mode as it may help to know if the upstream testcase can/should be adjusted to better support certain platforms.

Actually this looks like adept for backport to 8u, see JDK-8068026.
