test-format-util seems to be failing on i386

[evverx]

Yesterday I tried to turn on bionic-i386 (now that https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1829829 is fixed) and got the following:

293/497 test-format-util                        FAIL     0.17 s (killed by signal 6 SIGABRT)

As far as I can tell, it fails because "3T" can't fit into size_t on i386:

@iainlane judging by http://autopkgtest.ubuntu.com/running#pkg-systemd-upstream, it seems Ubuntu CI keeps running the tests for PR 12618, which was merged about a month ago. Could you stop it?
