x86, vmlinux.lds: unify parainstructions

Browse source 
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 ]
