bits/time64.h always sets __TIME64_T_TYPE to be __time_t when
__TIMESIZE == 64, so we can unconditionally use __TIME64_T_TYPE to
define __time64_t; we don’t need another conditional in bits/types.h.

Also move the definition of __time64_t next to the definition of
__time_t.

	* posix/bits/types.h (__time64_t): Unconditionally define
        as __TIME64_T_TYPE.  Move definition next to __time_t.
