go fmt with Go 1.17

[Didainius]

Go 1.17 introduced changes to how build tags are defined. gofmt automatically fixes that and this PR is just to make sure we are 1.17 compatible so that make build works.

Additionally it tunes sed command in test-tags.sh so that it gathers all tags and ignores or || sign in new build tag format.

A longer description.
Go 1.17 started to use new format of build tags (which we use to separate test cases). In Go 1.17 go fmt command automatically maintains two types of build tags - new and old one. That way the code is still compatible with older Go versions. go fmt (in Go 1.17) will also keep these build directives in sync (older format with newer one). Additionally go vet will capture if these tags are not in sync. Our GitHub workflow will run on Go 1.17 now and it will capture if any of submitted tags are not in sync.

Example of how new build directive looks (line1) and older one (line2)
