Fix #10394 Do not error on missing characters in "nullfont".

Add an exception to the conversion of "missing character" warnings into errors.

The PGF package deliberately uses the dummy font "nullfont" to suppress output.
Therefore, warnings about missing characters in "nullfont" are really only warnings.

Also updated the comment: "Missing character" warnigns are especially widespread
in XeTeX/LuaTeX but can also happen with "classical" 8-bit TeX.

Feel free to port this to branch.

#10394 Do not error on missing characters in "nullfont".
# "LaTeXing" seminar fails (except for LuaTeX) with
# Missing character: There is no 0 in font nullfont!
# due to a bug in PGF (https://sourceforge.net/p/pgf/bugs/314/)
# However, these warnings can be safely ignored as PGF deliberately uses
# "nullfont" to suppress output.
