remove aix61-ppc64 from CI

[richardlau]

Refs: libuv/libuv#2765

Remove references to aix64-ppc64 so that the machines can be freed up and potentially reimaged with an in-support version of AIX (either 7.1 or 7.2). We should no longer be build/testing on AIX 6.1 (which is out of support) and should already be build/testing on > AIX 7.1.

For the public test CI, based on https://github.com/nodejs/jenkins-config-test/ and the following shell script:

-bash-4.2$ grep aix61-ppc jobs/*  | awk -F'[/:]' '{ print "- [ ] "$2 }' | sort -u

These are the jobs that need updating:

• citgm-abi-smoker.xml
• citgm-smoker-nobuild.xml
• citgm-smoker-pipeline.xml
• citgm-smoker-private.xml
• citgm-smoker-v10.x.xml
• citgm-smoker-v12.x.xml
• citgm-smoker.xml
• llnode-pipeline.xml
• node-inspect.xml
• nodereport-continuous-integration-latest.xml
• node-stress-single-test.xml
• node-test-commit-aix.xml
• node-test-node-addon-api-new.xml
• node-test-node-addon-api.xml
• readable-stream-continuous-integration.xml
• readable-stream-pipeline.xml
• string_decoder-continuous-integration.xml
• string_decoder-pipeline.xml

I'll update these but I don't have visibility of the release CI/job backup repository so would need someone else (@sam-github ?) to update the release:

• check-java-version.xml
• iojs+release-joaocgreis.xml
• iojs+release-mdawson-major.xml
• iojs+release.xml

@richardlau what do I have to do?

[richardlau]

@sam-github run the bash script in the description for this PR but against https://github.com/nodejs/jenkins-config-release (which I assume you've now done as you've edited the list in) and then remove/update the references to aix61-ppc64 for those jobs (and if you could please check them off when done). I'll do the jobs on the test CI and then when they're all done PR a change to remove aix61-ppc64 from the VersionSelectorScript.groovy file.

[sam-github]

I unchecked the aix61-ppc64 label in configuration matrix for the ci-release jobs, the label was already unchecked for check-java-version.xml.

[richardlau]

Believe all references to aix61-ppc64 have been removed from both test and release (thanks @sam-github ) CI's. Will open a PR to update the VersionSelectorScript.groovy and select compiler scripts.
