benchtests: Make compare_strings.py output a bit prettier

Browse Source 
Make the column widths for the outputs fixed so that they look a
little less messy.  They will still look bad with lots of IFUNCs (like
on x86) but it's still a step forward.

	* benchtests/scripts/compare_strings.py (process_results):
	Better spacing for output.
