y2038: Use a common definition for shmid_ds

Browse Source 
Instead of replicate the same definitions from struct_shmid64_ds.h
on the multiple struct_shmid_ds.h, use a common header which is included
when required (struct_shmid64_ds_helper.h).

The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit semctl implementation.
