[PATCH 1/3] perf bench: Set more defaults in the 'numa' suite

Currently,

$ perf bench numa mem

errors out with usage information. To make this more user-friendly, let
us provide a minimum set of default values required for a test
run. As an added bonus,

$ perf bench all

now goes all the way to completion.
