toolbox: getevent: disable stdout buffering
So that the getevent output can be redirected and still be responsive
when events occur.
A good example is when using 'adb shell getevent' command, this latter
would only display the events when the buffer is full. With this patch
as soon as an event is received/printed, it is flushed to stdout.
