makeapi script is used to check if ipalib API is consistent with the known state in API.txt. When the API is changed, major API version should be updated. However, when new options/arguments/outputs were added to an ipalib command, `makeapi --validate' call did not capture this. This patch fixes this issue and ensures that also the last command in API.txt is checked (it was not before this patch). https://fedorahosted.org/freeipa/ticket/868
