Arm SPEv1.2 adds another 64-bits of event filtering control. As the
existing perf_event_attr::configN fields are all used up for SPE PMU, an
additional field is needed. Add a new 'config3' field.

Try not to have tools/ and kernel code in the same patch, else you'll
burden kernel developers into testing tools/, which so far has been
refrained.

I knew that, but assumed the header was special...
