B #3972: normalize the list of cpus (#3973)

Browse Source 
following the description in CPUSET(7) man page:

 List format
  The List Format for cpus and mems is a comma-separated list of 
  CPU or  memory-node numbers and ranges of numbers, in ASCII
  decimal.

   Examples of the List Format:

       0-4,9           # bits 0, 1, 2, 3, 4, and 9 set
       0-2,7,12-14     # bits 0, 1, 2, 7, 12, 13, and 14 set
