[bug#39605] bug#39603: go-ipfs 0.4.22 fails to build

[Jack Hill]

Hi,

It appears that go-ipfs 0.4.22 is not compatible with the recent upgrade 
to go 1.13. Fortunately, upstream has made a maintainance release that 
includes the support for go 1.13: 
https://github.com/ipfs/go-ipfs/releases/tag/v0.4.23

I've submitted a patch to update go-ipfs in 
https://issues.guix.gnu.org/issue/39605

Best,
Jack
