[2/3] benchtests: Add --no-header option to omit header

  From: Leonardo Sandoval <leonardo.sandoval.gonzalez@linux.intel.com>

Having raw output without header makes easier the interaction with
other tools, thus include an option to omit it.

	* benchtests/scripts/compare_string.py: Add --no-header
	option to omit header

Please change the help text to "Do not include the header in the output".

Also, if you're writing a tool to analyze the results, please also 
consider propose merging them into glibc if you think they could be of 
more general use.
