Add versioned variants of some environment variables

Browse source 
Improve parallel installability in setups like jhbuild by
providing versioned variants of some environment variables:

 GST_REGISTRY_1_0
 GST_PLUGIN_PATH_1_0
 GST_PLUGIN_SYSTEM_PATH_1_0
 GST_PLUGIN_SCANNER_1_0

will now be checked before checking the unversioned ones.
