[gnome-shell-sass] panel: Remove panel translucency

    panel: Remove panel translucency
    
    Since commit 447bf55e45b we turn the top bar translucent when
    free-floating. While this looks fancy and reduces the appearance
    of cutting into the available screen space, it has also had a
    negative effect on legibility.
    
    Nobody stepped up to address those issues in two years, so revert
    back to the fully opaque top bar.
