Userns requires idmap mounts or to opt-in for a slow and expensive chown. As idmap mounts support for overlayfs was merged in 5.19, let's add the slow_chown config for our CI. The config is harmless to keep it in new kernels, as if idmap mounts is supported, it will be just used. Whenever all our CI is run with kernels >= 5.19, we can remove this setting.
