The test suite was run as root, no wonder why my removing write access
has no effect. I got the test to pass with this, but then it fails
with
Can't write .prove (Permission denied) at /usr/share/perl/5.22/App/Prove.pm line 542.
Some more chown'ing or chmod'ing is required....

Subject: [PATCH] ci: don't accidentally run the test suite as root
This script assigns and adds a user named "ci" in a subshell so the
outer CI_USER is not affected. For some reason, CI_USER is actually
empty on Travis linux32 builds. This makes the following "su" useless
and the test suite is run as root.
Some tests may expect file/dir permissions to be respected. But root
rules all and ignores all. That could make tests fail.
