Set up font fallthrough for emoji

We set up a fonts.conf to specify Bitstream Vera for all my font
preferences with a fallback to the Noto Color Emoji. This should
standardize font/emoji support and my method falls back to system
fontconfig if these aren't font.

Then we swap alacritty and sway to monospace.
