build system: create fmap for UPDATE_IMAGE configurations, too

This fixes UPDATE_IMAGE builds, assuming that the fmap configuration in
the tree didn't change, at least as far as the CBFS regions are

Another option would be to synthesize the fmap related files from the
existing image, but that comes with other issues (eg. what about
updating images old enough that there is no fmap?) and is more complex,
so keep it simple, stupid for now.
