xtensa: Add time64 support.
- xtensa is the second architecture that supports
time64 inside uClibc-ng.
- Linux Kernel always uses 32bit time variables
inside `stat` structures, so there is a need
to use `st_atime`, `st_mtime` and `st_ctime` structures with the same
32bit-wide `tv_sec` and `tv_nsec` variables even if time64 is enabled.
