[PATCH v5 07/27] perf buildid-list: Use perf_tool__init

[Ian Rogers]

Reduce scope of build_id__mark_dso_hit_ops to the scope of function
perf_session__list_build_ids, its only use, and use perf_tool__init
for the default values. Move perf_event__exit_del_thread to event.[ch]
so it can be used in builtin-buildid-list.c.
