driver: fail to build on Windows with go < 1.13

kolyshkin · kolyshkin · commit da42a3033a39 · 2020-02-26T20:42:32.000-08:00
The next commit requires go 1.13 for Windows, so let's
guard against building this package with earlier golang
releases.

Note that since go 1.14 is out, go 1.12 is no longer supported.
