scripts/bloat-o-meter: fix percent on <1% changes
Python divisions are integer divisions unless at least one parameter is
a float. The current bloat-o-meter fails to print sub-percentage
changes:
Total: Before=10515408, After=10604060, chg 0.000000%
Force float division by using one float and pretty the print to two
significant decimals:
Total: Before=10515408, After=10604060, chg +0.84%
