Make 64-bit time_t unsigned

Browse source 
* 32-bit time_t should be unsigned because otherwise it wraps too
  soon. (in 2038)

* 64-bit time_t should be unsigned because it should be consistent
  within NuttX.

* While signed time_t seems more popular among other OSes, the
  consisitency within NuttX outweighs, IMO.
