Clean up profiles now that the base abstraction allows reading /proc/*/{auxv,status}

[intrigeri]

In r3626, to address https://launchpad.net/bugs/1658239, we've added read permission on @{PROC}/@{pid}/{auxv,status} to the base abstraction. On my system, I count 13 profiles that explicitly add such permissions themselves. They should be cleaned up.

And while we're at it, we should adjust the "glibc's *printf protections read the maps file" comment that r3626 didn't update.
