flimflam-test: Remove duplicate scripts from flimflam-test

To prevent developers from modifying these scripts, not knowing that more
recent code is in src/platform/shill/test-scripts, remove the scripts.
Leave a note in their place pointing to where they have gone.  In
time, we'll delete the whole package.

TEST=These scripts aren't being used anymore, because people have
noticed a problem where the migration missed a recently added script.
