Use CMake's built-in timestamp formatting.
It notably honors SOURCE_DATE_EPOCH if set, making for reproducible
output. For even better reproducibility, use UTC. (Unlike the date
command's output, the result is already always in English.) Extend
this approach to the book, introducing appropriately formatted
PDF_DATE and TODAY variables for its PDF metadata and title page
respectively and making make_pdf configurable.
