internal/uidriver/glfw: Bug fix: A window can never be 'maximized' on fullscreen

Browse Source 
When the window is fullscreen, calling MaximizeWindow never returned.
Apparently the attribute glfw.Maximized can never be true on the
fullscreen mode.

This change fixes the issue by checking the fullscreen state.
