[libmediaart] Remove --enable-nemo

[Carlos Garnacho <carlosg src gnome org>]

commit 9c2091d67d581fed07dae8dc4b0e0541bc6be3f8

    Remove --enable-nemo
    
    This flag was just enabling a codepath that sets QT_QPA_PLATFORM=minimal
    in the environment before constructing a QCoreApplication instance.
    
    This code path has no effect anyway: QT_QPA_PLATFORM only has an effect
    if you are using QGuiApplication.
