Move the logs from STDIO/STDERR to system log.

In this CL, the logging behaviors are modified.
In the original design, the STDOUT and STRERR are used. However,
to make the logs more accessible, the system log is used.

By using the LOG(X) apis, the logs will now go to /var/log/message

BUG=chromium:712706
TEST=Build package for Guado board and test if the update process is started correctly.
