Linux: overhaul io process fields

Browse Source 
- avoid UBSAN conversions
- print N/A on no data (i.e. as unprivileged user)
- fix rate calculation to show bytes (instead of a thousandth)
- print bytes as human number (i.e. 8MB) instead of 8388608
- stabilize sorting by adjusting NAN values to very tiny negative number
