Update crostestutils to use chromite.lib.cros_build_lib.
crostestutils is a build-time tool and as such should be updated to use
chromite. This CL removes the 2nd last dependency on the crosutils
cros_build_lib and moves us closer to being able to remove the module.
This CL also removes the last dependency on error_ok=True support in
chromite.lib.cros_build_lib.
BUG=chromium-os:24660, chromium-os:21287
