Fix stdout_sink_base::log's behavior inconsistency (#2646)

Browse Source 
* Fix stdout_sink_base::log's behavior inconsistency

It will flush every time when it if not defined _WIN32, but not in
Windows family.
We viewed the commit #48d4ed9 for fixing issue #1675 .
It seems missing this flushing operation in mistake.

* Use fflush at all operating system

* Remove redundant fflush from stdout_sink_base
