Subsequent patches will need to call perf_evlist__propagate_maps
without reference to a "target".  Add evlist->has_user_cpus to
record whether the user has specified which cpus to target
(and therefore whether that list of cpus should override the
default settings for a selected event i.e. the cpu maps should
be propagated)
