DTrace in a zone should see "cpu", "curpsinfo", et al
Users in zones cannot have the dtrace_kernel privilege, and thus cannot presently gain access to potentially interesting members of the DTrace variables curpsinfo, curlwpsinfo and curcpu.
Users with only dtrace_proc (and thus users in appropriately configured non-global zones) should be able to read any members of these variables that do not represent privilege escalation. This change enables that behaviour by allowing loads from restricted ranges within the current thread's proc_t, cred_t, etc.
