Fix the console performance issue

The IDF monitor waits for one second before printing the last
unterminated line. This is necessary for the correct filtering.
However, this causes poor performance, for example, in the case of the
system/console example.

This fix reduces the waiting time which improves the response time of
the console example and doesn't seem to influence the monitor filter.
