tools: util-linux: allow building with 32-bit time

Similar to several GNU tools, util-linux when built using meson
is configured by default to error when 64-bit time is not supported.

To solve this in the same way as standard configure scripts,
check for 64-bit time support ahead of time,
and allow 32-bit time when not supported.

In the future, the YEAR_2038 variable
can be used as a build prerequisite
instead of being used for configuration.
