tools/coreutils: remove 64-bit time disable flag
This was added to support building coreutils on host systems
that still only have 32-bit time support.
Because other tools now also require the flag for building
with 32-bit time when support for 64-bit time is not present,
this flag is now added to all host builds
on a variable basis using the same test before building,
so it can now be removed from specific tools.
