x86/alternative: Align insn bytes vertically

For easier inspection which bytes have changed.

For example:

feat: 7*32+12, old: (__x86_indirect_thunk_r10+0x0/0x20 (ffffffff81c02480) len: 17), repl: (ffffffff897813aa, len: 17)
ffffffff81c02480: old_insn: 41 ff e2 90 90 90 90 90 90 90 90 90 90 90 90 90 90
ffffffff897813aa: rpl_insn: e8 07 00 00 00 f3 90 0f ae e8 eb f9 4c 89 14 24 c3
ffffffff81c02480: final_insn: e8 07 00 00 00 f3 90 0f ae e8 eb f9 4c 89 14 24 c3

No functional changes.
