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.
