Subject: [PATCH] perf tools mem: Fix -t store option for record command

Michael reported 'perf mem -t store record' being broken.
The reason is latest rework of this area:
  commit acbe613e0c03 ("perf tools: Add monitored events array")

We don't mark perf_mem_events store record when -t store
option is specified.

Fixes: commit acbe613e0c03 ("perf tools: Add monitored events array")
