Since RHEL 7.4, nf_conntrack_proto_sctp module is compiled into the
kernel instead of as a module as the sctp support.
With recent changes in kmod puppet module, we've started seeing failures
loading the nf_conntrack_proto_sctp module while deploying OpenShift via
TripleO.
Commit [1] makes kmod puppet module load the kernel modules via systemd
when it is available, so systemd-modules-load.services fails with
"Failed to find module 'nf_conntrack_proto_sctp'".
