factory_test_init: split output into verbose log and console data

To support subshell execution (ex, gooftool) in a better way,
we should separate "log" and "console info".

This CL makes everything from autotest goes to factory.log, while lines with
"FACTORY" also goes to console for feedback to operators.

This CL must be applied with http://codereview.chromium.org/6736025/.

TEST=build a factory image and install;
     seeing messages appears in console window.
