lxc: lxc-test-parse-config-file failure on Jammy (retrieved value "" for config key "lxc.selinux.context")

[Po-Hsu Lin]

After bug 1943441 fixed for Impish, we're seeing this again on Jammy,
with lxc 1:4.0.12-0ubuntu2 from Jammy archive.

I can still see the issue from bug 1943441 with impish:linux. However, with one of the s390x systems (s2lp4 which is a lpar), I only get the second error reported on this bug:
