ksh: migrate to fork-folding year-prefix naming + recover pre-2007 history

Rename every ksh target from the internal shvr<Fork>-<tag> scheme to a flat,
date-ordered, Docker-tag-safe name folding the three forks (live 93u+m, ksh2020,
ksh93-history) into one sortable timeline. variants/ksh.sh derives the fork from
the name; checksum + patch dirs renamed to match (binary-neutral).

Recover six archaeological ksh93-history milestones (2004-2006) with per-version
reproducibility patches (float exponent/NaN-padding memset, mmap-worthy timing
pin, lcgen newof->calloc for the uninitialised LC_primary) and an amd64 fd-limit
pin (OPEN_MAX_CEIL).
