Use golangci-lint fmt for pkg/bindings

golangci-lint v2 introduced a new command, fmt, which runs configured
formatters (see formatters in .golangci.yml).

Use this for generated files. Drop separate goimports binary.

-Command goimports updates your Go import lines,
-adding missing ones and removing unreferenced ones.
-
-	$ go install golang.org/x/tools/cmd/goimports@latest
-
-In addition to fixing imports, goimports also formats
-your code in the same style as gofmt so it can be used
-as a replacement for your editor's gofmt-on-save hook.
-
-For emacs, make sure you have the latest go-mode.el:
-
-	https://github.com/dominikh/go-mode.el
-
-Then in your .emacs file:
-
-	(setq gofmt-command "goimports")
-	(add-hook 'before-save-hook 'gofmt-before-save)
-
-For vim, set "gofmt_command" to "goimports":
-
-	https://golang.org/change/39c724dd7f252
-	https://golang.org/wiki/IDEsAndTextEditorPlugins
-	etc
-
-For GoSublime, follow the steps described here:
-
-	http://michaelwhatcott.com/gosublime-goimports/
-
-For other editors, you probably know what to do.
-
-To exclude directories in your $GOPATH from being scanned for Go
-files, goimports respects a configuration file at
-$GOPATH/src/.goimportsignore which may contain blank lines, comment
-lines (beginning with '#'), or lines naming a directory relative to
-the configuration file to ignore when scanning. No globbing or regex
-patterns are allowed. Use the "-v" verbose flag to verify it's
-working and see what goimports is doing.
