x86, vmlinux.lds: unify parainstructions
32 bit:
- increase alignment from 4 to 8 for .parainstructions
- increase alignment from 4 to 8 for .altinstructions
64 bit:
- move ALIGN() outside output section for .altinstructions
None of the above should result in any functional change.
[ Impact: refactor and unify linker script ]
