[libpeas] Don't assume libpeas's stuff is initialized if python is.

    Don't assume libpeas's stuff is initialized if python is.
    
    We need to ensure we run our own initialization function even if python
    has already been initialized by someone else (either our host
    application or something like gtkparasite).
