BUILD: time: adapt the type of TV_ETERNITY to the local system

Some systems use different types for tv_sec/tv_usec, some are
signed others not. From time to time new warnings are reported
about implicit casts being done.

This patch ensures that TV_ETERNITY is cast to the appropriate
type in assignments and conversions.
