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.

build: agda-build-system: Do not rely on "locales" being present.

A "locales" package is no longer included in the 'standard-packages'

‘glibc-utf8-locales’ from ‘%final-inputs’."), which is made because glibc now
embeds a C.UTF8 locale.
