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.
