perf cpumap: Simplify equal function name

Rename cpu_map__compare_aggr_cpu_id() to aggr_cpu_id__equal(), the
cpu_map part of the name is misleading. Equal better describes the
function than compare.

Switch to const pointer rather than value as struct given the number of
variables in aggr_cpu_id().
