use 64-bit shmid_ds layout in the generic version of bits/shm.h

this layout is more common already than the old generic, and should
become even more common in the future with new archs added and with
64-bit time_t on 32-bit archs.

the duplicate arch-specific copies are not removed yet in this commit,
so as to assist git tooling in copy/rename tracking.
