    bitbake: toaster: fix imports to work for python 3
    
    Some APIs have been moved to other modules in python 3:
     getstatusoutput: moved from commands to subproces
     urlopen: moved from urllib2 to urllib.request
     urlparse: moved from urlparse to urllib.parse
    
    Made the imports work for both python versions by
    catching ImportError and importing APIs from different
    modules.
