Revert "TEST-19-CGROUP: Skip on opensuse"

[Werkov]

This reverts commit 60d064d.

systemd-run --wait --unit=test-0.service --property=DynamicUser=1 --property=Delegate= test -w /sys/fs/cgroup/system.slice/test-0.service/ -a -w /sys/fs/cgroup/system.slice/test-0.service/memory.oom.group

is suspicious as it only relies on test-0.service:MemoryAccounting=yes (or anything that enables memory controller in test-0.service) which isn't set on openSUSE.

Draft PR to troubleshoot the test.

Ref: #32439

@Werkov With meson from git you can debug locally with something like follows:

../meson/meson.py compile -C build mkosi && SYSTEMD_INTEGRATION_TESTS=1 ../meson/meson.py test -C build --no-rebuild -i TEST-19-CGROUP
