Fix getprivs and getsystem

This is a fix for crap and stupid stuff that I did half way through the
packet pivot code. I was working on some priv stuff at the same time,
and when I realised that the work I was doing was not sensible as part
of the packet pivot PR, I failed to revert my changes properly.

As a result I broke `getprivs` and `getsystem`. I am sorry. And I'm
ashamed.
