This should be done in a init script. This is a runtime configuration
and there is no reason to diverge procps package for it.

I see some possible ways to address it:

* make a qoriq-asfastpath-init recipe

 This would check the kernel, at runtime, and see if it is enabled. In
case it does, it uses sysctl to set the values accordingly.

* add a do_install_append *in kernel* which makes a
${sysconfdir}/sysctl.conf.d/99-as-fast.conf

 This makes this fine and install it when the kernel has it enabled.

So in no means changing procps seems the best alternative. It is
related *to the kernel* and may - and likely will - vary from one
machine to another.
