Add distbuild-morphology command.

This is useful to build releases using distbuild. It avoids having the
SHA1 fields in the artifact metadata files pointing to commits that
exist only on temporary build branches. It also avoids file:// URLs in
the repo fields. Note that the repo URL still points to the Trove used
by the distbuild network, rather than being an upstream URL pointing to
git.baserock.org.
