Define in_int32_t_range to check if the 64 bit time_t syscall should be used

Currently glibc uses in_time_t_range to detects time_t overflow,
and if it occurs fallbacks to 64 bit syscall version.

The function name is confusing because internally time_t might be
either 32 bits or 64 bits (depending on __TIMESIZE).

This patch refactors the in_time_t_range by replacing it with
in_int32_t_range for the case to check if the 64 bit time_t syscall
should be used.

The in_time_t range is used to detect overflow of the
syscall return value.
