vboot: Compile bootmode.c conditionally based on CONFIG_VBOOT

Currently, src/vboot/bootmode.c gets compiled even if vboot is disabled.
It seems that this was only done to support calling certain
developer/recovery mode functions in this case. There is no reason to
compile the whole file for that -- we can just differentiate with a
stub in the header instead, which is what other parts of coreboot
usually do for cases like this.
