In the cpu-partitioning profile, IRQ affinity change is already done
as part of the 'isolated_cores' option of the scheduler plugin, so
calling defirqaffinity is, at best, redundant. So let's remove the call.
In the realtime* profiles, it's essentially the same, except that tuna
was used instead of isolated_cores. So let's use built-in functionality
instead of tuna and drop calls to defirqaffinity.

Error message about no isolated cores set wasn't displayed,
because the current plugin_script code only logs messages written
to STDERR.
