t0006 & t5000: skip "far in the future" test when time_t is too limited

Git's source code refers to timestamps as unsigned long, which is
ill-defined, as there is no guarantee about the number of bits that
data type has.

In preparation of switching to another data type that is large enough
to hold "far in the future" dates, we need to prepare the t0006-date.sh
script for the case where we *still* cannot format those dates if the
system library uses 32-bit time_t.
