[grilo-plugins] tests: tmdb: Use the built plugins, not the installed ones.

    tests: tmdb: Use the built plugins, not the installed ones.
    
    By setting the GRL_PLUGIN_PATH environment variable in the code.
    Note that we have to copy the .xml file into the .libs directory
    to make this work. We will need to do that for other plugins when
    testing them too.
