output: Avoid thunking to 16bit mode in printf() if no vgabios

It is not necessary to call the vgabios if no vgabios has been
installed.  This reduces the amount of hardware accesses on qemu when
the bios is not initializing the display hardware, and it can reduce
the boot time by a couple of milliseconds.
