Ian Rogers fcb3b7c304 libperf event: Ensure tracing data is multiple of 8 sized 
[ Upstream commit b39c915a4f ]

Perf's synthetic-events.c will ensure 8-byte alignment of tracing
data, writing it after a perf_record_header_tracing_data event.

Add padding to struct perf_record_header_tracing_data to make it 16-byte
rather than 12-byte sized.

Fixes: 055c67ed39 ("perf tools: Move event synthesizing routines to separate .c file")
