    monitor-stream-src: Use cogl_framebuffer_finish()
    
    Even though cogl_framebuffer_flush() was supposed to be enough,
    it ends up creating streams with odd visual glitches that look
    very much like unfinished frames.
    
    Switch back to cogl_framebuffer_finish(), which is admittedly
    an overkill, but it's what works for now. There is anedoctal
    evidence showing it doesn't incur in worse performance.
