Fonts: documents use the craft-fonts Simplified Chinese face too (#888)

Builds with craft-fonts (releases, the FreeBSD job) put only its Japanese
faces in the document font database; Noto Sans CJK SC served the interface
alone. Simplified-only ideographs in a document then had no face unless the
system had one, and the run-level CJK pick from #567 found no face covering a
mixed run, which the FreeBSD job's
east_asian_run_uses_one_face_covering_the_whole_run caught. The Chinese craft
faces now follow the Japanese ones (Mincho stays first for Japanese text).

fallback_reads_each_installed_font_file_once_however_many_characters_miss
used U+30001.., part of which Noto Sans CJK SC maps (CJK Extension G); it now
uses Supplementary Private Use Area-A, which no font here maps.
