Modify au_test_harness and ctest to work from new location.
I'm leaving behind symlink in src/scripts/bin for these. I verified that the builder code that calls those symlinks still works correctly with these new paths. This required eliminating all references to __file__.
I have also removed dead code from ctest. I verified that this code is no longer used at all.

BUG=chromium-os:11172
TEST=Ran both ctest and cros_au_test_harness with x86-mario and x86-generic
commands from buildbot scripts.
