all: replace fmt.Sprintf("%d") with strconv.Itoa

This was found by running `git grep 'fmt.Sprintf("%d",' | grep -v test | grep -v vendor`

And this was automatically fixed with gotiti https://github.com/catenacyber/gotiti
and using unconvert https://github.com/mdempsky/unconvert
to check if there was (tool which fixed another useless cast)
