x86/headers: Clean up the kernel's struct sigcontext types to be ABI-clean

Browse source 
Use the __u16/32/64 types we standardized on in ABI definitions
and which other sigcontext related types are already using.

This will help unify struct sigcontext types between native
32-bit, compat and 64-bit kernels.
