    flatpak: Drop not yet usable Libretro cores
    
    BlastEm doesn't yet support snapshots, DOSBox-SVN needs work, and doesn't
    support snapshots either, MAME just doesn't work, Mednafen Saturn requires
    firmware, and PrBoom crashes because of missing data.
    
    Also drop BlastEm test.
