Mistaken authorship on some commits

[John Soo]

Hi Guix!

I think I am reported as the author of commits

0cc8cdbe1b0018ec37b1de9032c9eca884bedb6e
a97b943b5590c6406a85cb0f2f03fa69d7e3b7d8
c26fd5648c2a24dbd71f4c0851f8b5eced75e0f1

I did not author these, though it would have been likely.

Thank you so much, maintainers.

- John
