SRC test: Fix testbench execute command line plus cleanup

This patch fixes the command line sample rate parameters passing
into host testbench (-r & -R).

In my computer at least the print command of non-visible plots stopped
working into error so I disabled the print commant that creates PNG
graphics files. It's OK since the purpose of this script is batch testing.
The visible plot files can be enabled from SRC test script to see plots
if need for deep dive.

The patch includes also fix for text output for "help src_test". The
input and output word lengths were missing from sample command.
