build: gnu-build-system: Compress man pages with zstd.

The aim is to improve the efficiency of computing the man pages database,
which must decompress the man pages.  Zstd is faster than gzip, especially for
decompression, and has a similar compression ratio.

* gnu/packages/commencement.scm (%final-inputs): Add zstd.

Revert "gnu: coreutils: Disable 64-bit time_t on 32-bit systems."

This reverts commit 4eebb73295a8ffdaefcfb7940254ad9c18e4e5d4.

The ‘--disable-year2038’ flag appears to be unnecessary (tested on
i686-linux).  More importantly, it’s potentially harmful as it could
prevent rebuilds after year 2038 due to timestamp inconsistencies as
they wrap around, and could make the tools unusable altogether.
