Numpy needs these.
Also added the "present" directory, since the contents are the same as possible

Some linux commands depend on /sys/devices/system/cpu/possible, such
as 'lscpu'.
Add 2 knobs for cpu:
/sys/devices/system/cpu/possible
/sys/devices/system/cpu/online
Both the values are '0 - Kernel.ApplicationCores()-1'.
