This changes the behavior of ctest to try to grab the latest zip from the zip web pages if it can't use the latest link (due to IOError or none provided). It assumes they have an Apache server and they reference images using version->ChromeOS-version-.*.zip) for each board/channel.

BUG=7675
TEST=Ran it with -l "http://Doesnotexist" and also without a -l option. Added new unittests to test and ran them as well.

1) image_to_vm aborts because e2fschk requires a terminal to
be connected in order to check whether or not you want to repair the fs. Since
we always want this to be true, set -p
2) Clean up test harness to only verify the number of tests that passed on the
base image are the same on the update back to. This is because older images
have many tests that fail. I leave 10% as a reasonable number to pass.
3) Redirect output from autotest in run_remote_tests to stderr so it gets
logged in a calling script that captures stdout.
