perf trace: Make evlist__set_evsel_handler() affect just entries without a handler Renaming it to evlist__set_default_evsel_handler(), to better reflect what we want to do, which is to set a default handler for events we still haven't set a custom handler, like the ones for "msr:write_msr", etc that are coming soon.
