[LTP] [PATCH] numa01.sh: unset default cpuset awareness before verify physcpubind

[Shizhao Chen]

On systems with cpu isolation configured (a very common technique used in the
real time kernel), $run_on_cpu may happen to be an isolated core and hence
unaccessible to numactl.

Unset default cpuset awareness with --all, so numactl can use all possible
CPUs/nodes for following physcpubind settings.
