Since commit edf319e[1], we're dynamically adjusting column width of
"CPU%", showing single digit precision also for values greater than
"99.9%" makes "CPU%" column consistent with all other values.

Change "Process_printPercentage()" function's logic to always display
value (i.e. "val") with single precision. Except when value is greater
than "99.9%" for columns like "MEM%", whose width is fixed to "4" and
value cannot go beyond "100%".
Credits: @Explorer09, thanks for the patch[2] to fix title alignment
issue.
