[pitivi] build: Don't attempt locale-uninstalled bits if DESTDIR is set

    build: Don't attempt locale-uninstalled bits if DESTDIR is set
    
    This breaks the build in Continuous, because it has a read-only bind
    mount outside of the explicitly provided $DESTDIR, and we were
    attempting to write files outside of that area.
