[PATCH 1/4] gputop: print percentage number

[Lucas De Marchi <lucas.demarchi@intel.com>]

Besides printing the bar, also print the raw number for easy
visualization of small quantities. While at it, make sure gputop still
works with small console widths.

v2: Use %5.1f instead of %.1f so it also aligns the non-decimal part
