signal: Remove non-uapi <asm/siginfo.h>

By moving the kernel side __SI_* defintions right next to the userspace
ones we can kill the non-uapi versions of <asm/siginfo.h> include
include/asm-generic/siginfo.h and untangle the unholy mess of includes.

[ tglx: Removed uapi/asm/siginfo.h from m32r, microblaze, mn10300 and score ]
