citgm/stress jobs do not select compiler for AIX on v10.x/master

Refs: nodejs/node#20137 (comment)

The stress job appears not to be using the compiler selector script added by #1240 so it's using the wrong level of gcc on AIX for master/v10.x.

e.g., https://ci.nodejs.org/job/node-stress-single-test/1825/nodes=aix61-ppc64/consoleFull

16:38:06 WARNING: C++ compiler too old, need g++ 4.9.4 or clang++ 3.4.2 (CXX=g++)

This apparently goes for CITGM as well: https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/1390/nodes=rhel72-s390x/console

Fixing the stress job.

@gdams can you update the CITGM jobs, they need to use

rm -rf build
git clone https://github.com/nodejs/build.git
. ./build/jenkins/scripts/select-compiler.sh

For all platforms (selection is currently done on PPC, s390 and AIX, but will be on others in the future). In addition for AIX if there is a CC= definition it should be removed as that is now set by the selection script.

Stress job fixed.

Ping @gdams re. the CitGM jobs ^

Note that this is affecting the v10.2.0 PR: nodejs/node#20724 (comment)

[mhdawson]

@gdams can you prioritize updating the Citgm jobs?

[gdams]

I have added this script to the citgm-smoker job

thanks all! Can this be considered fixed now?
