[PULL 07/17] qom: Correct error values in two contracts

[Eduardo Habkost]

From: Markus Armbruster <armbru@redhat.com>

object_property_get_bool()'s contract claims it returns NULL on error.
Pasto; it returns false.

object_property_get_int()'s contract claims it returns "negative".  It
actually returns -1.  All the other object_property_get_FOO()
contracts specify the exact error value, so do the same here.
