  -----------
  [sanitizer] Undef _TIME_BITS along with _FILE_OFFSET_BITS on Linux

On 32-bit glibc>=2.34 systems using 64bit time_t build fails because
_FILE_OFFSET_BITS is undefined here but _TIME_BITS is still set to 64

Fixes

```
/usr/include/features-time64.h:26:5: error: "_TIME_BITS=64 is allowed
 only with _FILE_OFFSET_BITS=64"
| #   error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"
|     ^
| 1 error generated.
