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

[leonardo dot sandoval dot gonzalez at linux dot intel dot com]

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
