Title: DOC: signal: Tweak sosfilt example to ensure an illustrative plot is generated.

This fixes the example code so that a plot is included in the HTML docs. I used a different filter with different parameters so the plot clearly shows the "correct" impulse response generated using the SOS filter and the unstable impulse response generated using the full transfer function.
