perf stat: Fix a segfault with --per-cluster --metric-only

Browse Source 
[ Upstream commit caa463bb79 ]

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: cbc917a1b0 ("perf stat: Support per-cluster aggregation")
