[CI] GC logging JVM flags cause failures on Java 9

When our integration tests try to start up ES, they fail due to the PrintGCDateStamps flag

Node 0 output:
|-----------------------------------------

Relates to #27610

I think the change that has been made probably works for production but not for the integration tests.

The integration tests now fail with this error:

08:52:44 |  [log]

08:52:44 |    Error: Could not create the Java Virtual Machine.

An example of this is https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+java9-periodic/4989/console

I think the problem is that the JVM is being told to log to /var/log/elasticsearch, but for the integration tests the rpm is installed into a sub-directory of the build directory, so the directory that actually exists is distribution/rpm/build/cluster/integTestCluster node0/rpm-extracted/var/log/elasticsearch.

This one is basically the same problem but when testing the deb rather than the rpm: https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+6.x+java9-periodic/1609/console

@droberts195 This is tracked in #26062 (see comment). In short, the proposal in that issue is stop exploding these archives and starting Elasticsearch from them as that is not how they are intended to be used (instead, installed via a package manager and started as a service). So we need to disable these integration tests for the RPM and the Debian (we already have tests that they work in the packaging tests). I'm going to re-close this in favor of that one.

I opened #27725.

I get the following error, when using OpenJDK 9, Ubuntu 16
