numa: add a sysctl for numa_balancing
Add a working sysctl to enable/disable automatic numa memory balancing at
runtime.
This allows us to track down performance problems with this feature and is
generally a good idea.
This was possible earlier through debugfs, but only with special debugging
options set. Also fix the boot message.
