Merge bitcoin/bitcoin#29846: guix: replace GCC unaligned VMOV patch with binutils patch

a0dc2ebcda9e33aa5320221cd4ea371f84d221fd guix: replace GCC unaligned VMOV patch with binutils patch (fanquake)

Pull request description:

  Rather than invasively patching GCC, given we have binutils 2.38 available, we can patch it to flip the default for
  `-muse-unaligned-vector-move`.

  A 1 line binutils patch, is much more maintainable than the ~300 line patch into GCC. It's also a slight inprovement in regards to patching out ualigned instructions in the release binaries. For comparison:
  Master:
  ```bash
  objdump -D bin/*.exe | rg "vmova|vmovdqa|vmovaps|vmovapd|vmovdqa64|vmovdqa32"
  141b8be20: c5 f8 28 1a                 vmovaps(%rdx), %xmm3
  1420564b3: c5 79 29 36                 vmovapd%xmm14, (%rsi)
  1403060f3: c5 79 29 36                 vmovapd%xmm14, (%rsi)
  140792b13: c5 79 29 36                 vmovapd%xmm14, (%rsi)
  140cb0693: c5 79 29 36                 vmovapd%xmm14, (%rsi)
  1415ea0f3: c5 79 29 36                 vmovapd%xmm14, (%rsi)
  ```
