generator: Fix domainCheckpoint.listAllChildren()

    virDomainCheckpoint(dom, _obj)
expects a reference to the virDomain as its first argument, but
    virDomainCheckpoint.listAllChildren()
passes `self` instead:

libvirt.py:7056: error: Argument 1 to "virDomainCheckpoint" has incompatible type "virDomainCheckpoint"; expected "virDomain"

>>> import libvirt
>>> con = libvirt.open('test:///default')
>>> dom = con.lookupByName("test")
>>> first = dom.checkpointCreateXML("""<domaincheckpoint><name>First</name></domaincheckpoint>""")
>>> second = dom.checkpointCreateXML("""<domaincheckpoint><name>Second</name></domaincheckpoint>""")
>>> child, = first.listAllChildren()
>>> second.domain()
<libvirt.virDomain object at 0x7f828d777b80>
         ^^^^^^^^^
>>> child.domain()
<libvirt.virDomainCheckpoint object at 0x7f828d8160a0>
         ^^^^^^^^^^^^^^^^^^^
