build-system/go: Use go-1.17 by default.

Build all Go packages with go-1.17 by default.  Explicitly specify an
older Go version in packages which cannot build with go-1.17.

* gnu/packages/golang.scm (go): Update from 'go-1.14' to 'go-1.17'.
* gnu/packages/docker.scm (docker)[native-inputs]: Explicitly use 'go-1.14'.
* gnu/packages/ipfs.scm (go-github-com-ipfs-go-ipfs-cmdkit-files)[arguments]:
Explicitly use Go 1.16.
(go-ipfs)[arguments]: Use the default version of Go.
* gnu/packages/syncthing.scm (syncthing)[arguments]: Likewise.
* gnu/packages/admin.scm (runitor)[arguments]: Likewise.
