bpf/tests: Use migrate disable instead of preempt disable
Replace the preemption disable/enable with migrate_disable/enable() to
reflect the actual requirement and to allow PREEMPT_RT to substitute it
with an actual migration disable mechanism which does not disable
preemption.
[ tglx: Switched it over to migrate disable ]
