ps: enabled sort with 'utilization' related specifiers

When %CUU was added, in the commit referenced below, I
stated that 4 similar specifiers already existed. Well
I misspoke since there is actually 5 including 'util'.

Each of those fields had no sort capability. Since the
values are dynamically calculated, they were forced to
use 'PIDS_extra' as the format_array 'sr' designation.

Now each will use 'PIDS_UTILIZATION' and be sort-able.

[ yes, sometimes the calculated values could contain ]
[ reaped children while the sort field does not. but ]
[ such disparity depends on obscure bsd/gnu options. ]
