Build fails with missing go.sum entry

[dhx]

Hi @metal3d,
thanks for this great project!

Trying to build it (with make build) I ran into this error:

go: github.com/Microsoft/go-winio@v0.5.2: missing go.sum entry; to add it:
	go mod download github.com/Microsoft/go-winio
go: github.com/Microsoft/go-winio@v0.5.2: missing go.sum entry; to add it:
	go mod download github.com/Microsoft/go-winio

Which seems to be a variation of this issue:
golang/go#44129

Following the suggestion to add the -mod=mod parameter to the build commandline seems to fix the issue for me.

You can use my version resolved Here or in #3.
