Description

Found in T120349, the localisation cache for qunit jobs is shared between runs. That is because it is written to /tmp.

The web env does not have TMPDIR injected. We need to:

have mediawiki.d to explicitly set $wgTmpDirectory - https://gerrit.wikimedia.org/r/256912
point localisation cache to a known dir

hashar set Security to None.

Change 256912 merged by jenkins-bot:
mw-apply-settings: set $wgTmpDirectory explicitly

Had to fix the script a bit more:

https://gerrit.wikimedia.org/r/256913	mw-apply-settings: fix duplicate ?> php closing tag
https://gerrit.wikimedia.org/r/#/c/256914/	mw-apply-settings: no PHP opening tag either

Setting $wgTmpDirectory = '/mnt/home/jenkins-deploy/tmpfs/jenkins-0';

Might have caused T120824
