scripts/ Fall back to `git clone` if morph isn't available
This is a quick fix to allow the script to be run without dependence on morph. As discussed on IRC, since it isn't a simple problem finding a way to safely allow access to caches from different build tools, such a solution hasn't been attempted. When falling back to `git clone`, this change prevents the script from using an existing cache, generating its own instead by cloning from the Baserock cache server, which takes longer. Also add automatic creation of REPOS_DIR if it doesn't exist. Change-Id: Id4b0977a2cae90068b6c2e2fd0c62470287bdfcb
