[TASK] gitlab-ci: Activate check permissions script

Since moving to gitlab, script checkFilePermissions.sh
was inactive due to a gitlab detail that leads to
funny permissions of cloned files.

This can be suppressed with a gitlab feature toggle.

The patch activates that toggle, activates the test
script and fixes a couple of files that slipped in
with broken permissions meanwhile.
