Reproduces both locally and on CI hosts.

Why is the CI green then?

Because #6578

How do we fix this?

Option 1

1. Somehow fetch golang.org/x/tools and it's development into Nix
2. Make it available for the gomobile

Option 2

1. go get golang.org/x/tools
2. import _ "golang.org/x/tools/go/packages" somewhere in code (to prevent go mod tidy to remove the dependency)
3. make vendor
4. Set GO111MODULE=on for statusgo-ios and -android targets

This requires proper gomobile's support of vendoring.

• x/mobile: does not work with Go 1.22 if a vendor folder is present, even with the GO111MODULE=off workaround golang/go#67927

Perhaps we should try this fix:

• cmd/gomobile: add golistflags flag golang/mobile#105
