[COMMITTED] benchtests: Avoid a display error when running in text terminal
Commit Message
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.
