    build: add missing patch named in flatpak manifest.
    
    I did not commit on purpose because this is actually to be found in the
    official flathub repository for GIMP (the concept being to keep the
    stable and nightly manifests as sync-ed as possible) and I thought there
    is no need to duplicate data. But since this is apparently confusing
    people (cf. !91), let's just push it.
    
    Note that even though this patch is taken from the org.octave.Octave
    flatpak package, it is actually slightly different (I tweaked it because
    we needed to build even less options from SuiteSpace than they do
    apparently).
