benchtests: Add --no-diff and --no-header options

Browse Source 
Having a string comparison report with neither diff numbers nor header
yields a more useful output to be consumed by other tools.

	* benchtests/scripts/compare_string.py: Add --no-diff and --no-header
	options to avoid diff calculation and omit header, respectively.
	(main): process --no-diff and --no-header
