Downgrade warning about missing libseccomp

We currently log at warning level:
/usr/lib/systemd/system/systemd-udevd.service:56: System call bpf cannot be
  resolved as libseccomp is not available, ignoring: Operation not supported

In the initrd, or in minimal installations, not installing libseccomp is
reasonable, depending on various other choices. We shouldn't make fuss
about this.
