backup: Add virsh-checkpoints test

Similar to virsh-snapshots. Provides decent coverage of the checkpoint
API, the test driver implementation, and the virsh access to the API.
A later patch will worry about testing that snapshots and checkpoints
are mutually exclusive (in part so it is easier to revert that when we
finally implement the interaction and lift that restriction).
