benchtests: Avoid a display error when running in text terminal

Browse Source 
The compare_strings.py script generates a graph for the benchmarks it
performs a comparison on and that fails if X is not available.  Avoid
the error and ensure that only the graph is generated and saved as a
PNG file.

	* benchtests/scripts/compare_strings.py: Avoid display error
	when generating graph.
