x86: convert trivial headers to asm-generic version
For these nine header files, the asm-generic version should be semantically identical to what is in x86. Change the contents to be binary identical, for better review.

* The msqid64_ds structure for i386 architecture.

* msqid64_ds was originally meant to be architecture specific, but

* everyone just ended up making identical copies without specific
|
||||
* optimizations, so we may just as well all use the same one.
|
||||
*
|
||||
* 64 bit architectures typically define a 64 bit __kernel_time_t,
|
||||
* so they do not need the first three padding words.

* On big-endian systems, the padding is in the wrong place.

* - 2 miscellaneous 32-bit values
