[PATCH 2/2] perf stat: Fix a segfault with --per-cluster --metric-only

[Namhyung Kim]

The new --per-cluster option was added recently but it forgot to update
the aggr_header fields which are used for --metric-only option.  And it
resulted in a segfault due to NULL string in fputs().

Fixes: cbc917a1b03b ("perf stat: Support per-cluster aggregation")
