crostestutils: Fix lint errors in files under au_test_harness and ctest
The result is `cros lint au_test_harness/*.py` and `cros lint ctest/*.py` don't
complain. There are over 900 lint errors in files under other directories, but I
don't forsee myself touching any of them in the near future, so I am leaving
them alone...
BUG=None
TEST=`cros lint`, manual ctest run, and trybot
