lxc: lxc-test-parse-config-file failed (failed to set config item)

[Po-Hsu Lin]

With bug 1943441 (expected value and retrieved value do not match) fixed with lxc 1:4.0.12-0ubuntu1 on Jammy (still exist on F / I)

Now this test on Jammy with lxc 1:5.0.0~git2209-g5a7b9ce67-0ubuntu1 will fail with:
 Running '/tmp/lxc-pkg-ubuntu/src/tests/lxc-test-parse-config-file'
 parse_config_file.c: 49: set_get_compare_clear_save_load: failed to set config item "lxc.selinux.context" to "system_u:system_r:lxc_t:s0:c22"

 parse_config_file.c: 49: set_get_compare_clear_save_load: failed to set config item "lxc.seccomp.profile" to "/some/seccomp/file"

Thanks!
I have checked with our test result, this is not affecting newer kernels any more.
But it's still visible <= Jammy (lxc-5.0.0~git2209-g5a7b9ce67). Looks like we will need to backport this.
