a72fe0afa1 perf tests attr: Add proper return values 
The record command now properly returns the status of the tracee if
there's any. We need to properly set the expected return value of the
tracee in the attr tests.

3aa5939d71 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.
