run-tests: replace inline python handling with more native scheme

Normally changes in tests are reported like this in diffs:

   $ cat foo
-  a
+  b

Using -i mode lets us update tests when the new results are correct
and/or populate tests with their output.

But with the standard doctest framework, inline Python sections in
tests changes instead result in a big failure report that's unhelpful.
So here, we replace the doctest calls with a simple compile/eval loop.
