pull in packaging for emojione, add back fontconfig
Focal package for emojione has deleted "56-emojione.conf" with a maintainer script since 18.04. Also we used a modified version to avoid replacing the font with dejavu - this fontconfig file is needed for the color glyphs to take preference on our older qt.
adding back in this file will fix the regression in displaying the current color emoji.
