Bug 1409: GNU/Linux DRM Console: Clear stdin before exit and don't act on stdin in vsync-wait-loop

User input during test from the console will also end up in stdin of the console after the java application has been closed.
This is not only annoying, but also a security concern, as the input gets executed if containing a CR.

Further, the vsync-wait-loop shall ignore stdin.
