scripts/bloat-o-meter: don't fail with division by 0

Under some circumstances it's possible to get a divider 0 which crashes the script. Traceback (most recent call last): File "linux/scripts/bloat-o-meter", line 98, in <module> print_result("Function", "tTdDbBrR", 2) File "linux/scripts/bloat-o-meter", line 87, in print_result (otot, ntot, (ntot - otot)*100.0/otot)) ZeroDivisionError: float division by zero Hide this by checking the divider first.
