test-interactive: use stable EOL in various file generating routines

The seq.py and shell echo redirected to a file ends up with platform
specific EOL, which throws off the hash when the file is committed to
the test repo on Windows. The other option is to glob the hashes, but
the ability to see if they have changed might point out problems that
would otherwise be missed.

#   seq START STOP        [START, STOP] stepping by 1
#   seq START STEP STOP   [START, STOP] stepping by STEP
