Updating vcs to latest version

vcs had a release due to a CVE. This updates to the latest version
that mitigates the CVE.

Note, the Makefile was updated so that `make build` would build
without cgo just like gox does in the CI pipeline. They should
both build without cgo so we can catch issues before merging to
master where a canary build would pick up the problem.
