Lennart Poettering 3c19d0b46b units: restrict namespace for a good number of our own services
Basically, we turn it on for most long-running services, with the
exception of machined (whose child processes need to join containers
here and there), and importd (which sandboxes tar in a CLONE_NEWNET
namespace). machined is left unrestricted, and importd is restricted to
use only "net"
