- Remove PUA character for 'unknown flag' from cmap.
Unfortunately, the contorted build process means we can't do this where
we do our other cmap munging-- font.getGlyphID dies in emoji_builder
if we remove it from the cmap in add_glyphs.py. So we remove it at
the end of emoji_builder.
- Forgot to remap one territory flag, missed it in the spreadsheet. Also
corrected a typo where I remapped the same flag twice. Sorted the flags
in key alpha order.
