[mutter/wip/carlosg/tablet-mode-osd] core: Use b/w unicode for tablet mode OSD

    core: Use b/w unicode for tablet mode OSD
    
    This unicode was initially meant to be b/w, but fonts and pango
    eventually had another plan and we ended up with color glyphs
    being used here, so we get strings like "⚫⚪⚪⚪". Change the
    unicode used to ensure these are simpler b/w glyhps like
    "● ○ ○ ○" that are easier to read on the OSD (and maybe even a
    bit less ugly).
