perf record: Avoid synthesizing mmap() for all processes in per-thread mode
A bug was introduced by commit c45c6ea2e5c57960dc67e00294c2b78e9540c007. Perf record was scanning /proc/PID to create synthetic PERF_RECOR_MMAP entries even though it was running in per-thread mode. There was a bogus check to select what mmaps to synthesize. We only need all processes in system-wide mode. Cc: David S.
