perf stat: Add requires_cpu flag for uncore
Uncore events require a CPU i.e. it cannot be -1.
The evsel system_wide flag is intended for events that should be on every
CPU, which does not make sense for uncore events because uncore events do
not map one-to-one with CPUs.
These 2 requirements are not exactly the same, so introduce a new flag
'requires_cpu' for the uncore case.
