apparmor: fix rlimit for posix cpu timers
[ Upstream commit 6ca56813f4a589f536adceb42882855d91fb1125 ]
Posix cpu timers requires an additional step beyond setting the rlimit.
Refactor the code so its clear when what code is setting the
limit and conditionally update the posix cpu timers when appropriate.
Fixes: baa73d9e478ff ("posix-timers: Make them configurable")
