DTrace in a zone should have limited provider access
Users in zones cannot have the dtrace_kernel privilege, and thus cannot presently utilise various stable probe providers; in particular: proc, sched, vminfo and sysinfo.
This change allows SDT probes to specify that they may be enabled within a zone, but with potentially no access to probe arguments to prevent privileged information escaping.
