Smack: ptrace capability use fixes
[ Upstream commit dcb569cf6ac99ca899b8109c128b6ae52477a015 ]
This fixes a pair of problems in the Smack ptrace checks
related to checking capabilities. In both cases, as reported
by Lukasz Pawelczyk, the raw capability calls are used rather
than the Smack wrapper that check addition restrictions.
In one case, as reported by Jann Horn, the wrong task is being
checked for capabilities.
