Subject: scripts/decode_stacktrace.sh: code: preserve alignment

With lines having a code to decode, the alignment was not preserved for
the first line.

With this sample ...

  [   52.238089][   T55] RIP: 0010:__ip_queue_xmit+0x127c/0x1820
  [   52.238401][   T55] Code: c1 83 e0 07 48 c1 e9 03 83 c0 03 (...)

... the script was producing the following output:

  [   52.238089][   T55] RIP: 0010:__ip_queue_xmit (...)
  [ 52.238401][ T55] Code: c1 83 e0 07 48 c1 e9 03 83 c0 03 (...)

That's because scripts/decodecode doesn't preserve the alignment.  No need
to modify it, it is enough to give only the "Code: (...)" part to this
script, and print the prefix without modifications.

With the same sample, we now have:

  [   52.238089][   T55] RIP: 0010:__ip_queue_xmit (...)
  [   52.238401][   T55] Code: c1 83 e0 07 48 c1 e9 03 83 c0 03 (...)
