time: Add padding for the timespec if required
If we are running on a 32-bit system with a 64-bit time_t we need to ensure there is padding around the tv_nsec variable. This is requried as the timespec is #defined to the __timespec64 struct. * time/bits/types/struct_timespec.h: Add padding for the timespec if required.
