update_engine: Add helpful messages about lsb-release file.
In some unit tests we either don't have /etc/lsb-release or we don't
have a real clock and the (non-fatal) error messages about this can be
confusing. Rectify this by pointing out that these error messages may
occur in some unit tests.
BUG=chromium:401862
TEST=Unit tests pass.
