CI: Set slow_chown for overlayfs snapshotter

Browse Source 
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.
