Hi Guix!

After a few weeks of working on go-team it's ready for the final review
and merge to master.

My target was to update and move packages from (gnu packages golang) to
logical submodules and prepare bare minimal refreshed amount to complete
Prometheus packaging.

* Findings and potential refresh blockers

During refresh I've faced with go packages which still include vendor
directory and due to a large packaging efforts requiring to unbundle
them all might need some efforts distribution among volunteers.

Me and Artyom unbundling Kubo in our leisure time but the final step
(boxo) requires at least 300+ new packages.

- bitmask                       : 0.21.11->0.24.8 requires go-github-com-xtaci-kcp-go
- chezmoi                       : 1.8.10->2.52.2, 34+ new packages
- go-github-com-google-cadvisor : 0.0.0-0.2ed7198->0.50.0 216+ new packages
- go-github-com-ipfs-boxo       : to unbundle from Kubo, 218+ new packages
- go-github-com-spf13-afero     : 1.2.2->1.11.0, 194+ new packages
- go-github-com-spf13-viper     : 1.7.0->1.19.0, 225+ new packages
- go-github-com-xtaci-kcp-go    : to update bitmask, 200+ new packages
- rclone                        : 1.52.3->1.68.0, 348+ new packages
- restic                        : 0.9.6->0.17.1, 221+ new packages

Some of them may intersect.
