perf record: Make per-cpu mmaps the default.
This affects the -p, -t and -u options that previously defaulted to
per-thread mmaps.
Consequently add an option to select per-thread mmaps to support the old
behaviour.
Note that per-thread can be used with a workload-only (i.e. none of -p,
-t, -u, -a or -C is selected) to get a per-thread mmap with no
inheritance.
