CI/dist-modules: Use `actions/checkout@v2`

The test/checkout does work with `actions/checkout@v2` so use it instead
of 'checkout@v1'. (v2 is faster because it does a shallow clone and doesn't
fetch the tags.)

(My *assumption* on why `checkout@v1` was used: `checkout@v2` does not work
 when a 32-bit container is used on a 64-bit host. In these tests it uses
 a 64-bit container and that does work.)
