cbfs: don't load x86 programs over the top of read-only media
On x86 the early stages are currently execute-in-place which means they live in the memory-mapped spi flash. However, when loading romstage from verstage the romstage is execute-in-place so it's unnecessary to write over a read-only media -- not to mention writing to read-only memory is wrong to begin with. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados. Noted reduction of 20ms when loading romstage.
