Add a default path for vbt.bin

FSP_GOP needs a vbt.bin to work but before this patch it was able to
build with the default configuration which was an empty path for
vbt.bin.

To make Jenkins happy don't select FSP_GOP by default, at least until
all boards have the proper vbt blobs in the blobs repo.
