Title: Reinstate update_lockfile flag from berks 2

In berks 2 there was a flag update_lockfile on install/upload that would prevent the Berksfile.lock from being created. This flag is not present in berks 3, since I relied on it in my own code I would appreciate if you considered merging this PR which adds the flag to berks 3.
