perf tools: display the new PERF_RECORD_BPF_METADATA event
Here's some example "perf script -D" output for the new event type. The
": unhandled!" message is from tool.c, analogous to other behavior there.
I've elided some rows with all NUL characters for brevity, and I wrapped
one of the >75-column lines to fit in the commit guidelines.
