pdtest: use less expensive Python routine to get text differences
Python ships with a difflib(3) module which is used in the pdtest(1) utility. The Differ.compare() routine is rather expensive, especially when the set of input text becomes "large" (a few thousand lines). Use the less expensive unified_diff() routine instead which does not suffer from that cost. From the sigrok-test perspective the resulting data is as usable.
