rootful: do not set XDG_RUNTIME_DIR for cni plugins
The dnsname plugin tries to use XDG_RUNTIME_DIR to store files.
podman run will have XDG_RUNTIME_DIR set and thus the cni plugin can use
it. The problem is that XDG_RUNTIME_DIR is unset for the conmon process
for rootful users. This causes issues since the cleanup process is spawned
by conmon and thus not have XDG_RUNTIME_DIR set to same value as podman run.
Because of it dnsname will not find the config files and cannot correctly
cleanup.
To fix this we should also unset XDG_RUNTIME_DIR for the cni plugins as
rootful.
