examples: Don't print text when using dual 3D FB mode

Browse Source 
When using dual 3D DMA mode the console is setup to use memory in the
middle of SUB background VRAM. This is what holds the text that you can see
on the screen.

When switching to FB mode, the console is never reconfigured (when
switching to regular dual 3D mode it is reconfigured). This means that any
printf will write to the middle of background VRAM, which is used as
framebuffer. This will manifest itself as a blue horizontal line in the
middle of the screen.

This patch fixes the examples to not print text when using FB mode.
