Create a latest link to point at newest image

Browse Source 
build_image creates it after a successful build, and get_latest_image
can use it if it exists. Fall back to old behavior for now when there
are directories without a link.

BUG=none
TEST=Try building an image, check link. Rebuild, check new link.
