Description

Joyent fixed a bug with cross-zone USDT probes, we should incorporate their fix

dtrace_enabling_matchall() is run in the context of the process containing the probe (the NGZ), but performs permission checks as if it were in the context of the the consuming process (the GZ), leading it to miss new USDT probes in the NGZ. The permission check needs to decide visibility based on the permissions of the enabling, rather than the zone in which the current process is operating.
