Provide a default implementation for set/get shallowCommits on DfsObjDatabase

Jgit change https://git.eclipse.org/r/c/jgit/jgit/+/193329 adds an implementation for get/set shallow commits in ObjectDatabase. This failed gerrit's acceptance tests since there is no default implementation for them in DfsObjDatabase.
