perf evlist: Fix splice_list_tail() not setting evlist 

Commit d49e469507 ("perf evsel: Add a backpointer to the evlist a
evsel is in") updated perf_evlist__add() but not
perf_evlist__splice_list_tail().

This illustrates that it is better if perf_evlist__splice_list_tail()
calls perf_evlist__add() instead of duplicating the logic, so do that.
This will also simplify a subsequent fix for propagating maps.
