libc/time: Reduce _MAXYEAR in 32 bit systems

We use a simplified overflow check, and we just check for
the maximum year where we can fully encode any date, and
while UNIX time can encode until 2038 with 32 bits it can
encode only until January 19th so if we want to maintain
the simple check that we have then we have to decrease the
maximum year to 2037.
