Fix failing issues with vendoring as well as compiling

Something within golang.org/x/sys messed up and it doesn't help that we
have three different projects using different versions.

This vendor update specifies a golang.org/x/sys as well as fixes the
previous compiling issues with Windows/Linux/macOS builds.

See issue:

```sh
gox -osarch="darwin/amd64 linux/amd64 linux/arm windows/amd64"
