docker: don't rely on submodules existing in the main checkout
When building the tarball to pass into the docker/vm test image, the code relies on the git submodules being checked out in the main checkout. ie if the developer has not run 'git submodule update --init dtc' many of the docker tests will fail due to the libfdt package not being present in the test images. Patchew manually checks out the dtc submodule in the main git checkout, but this is a bad idea. When running tests we want to have a predictable set of submodules included in the source that's tested. The build environment is completely independent of the developers host OS, so the submodules the developer has checked out should not be considered relevant for the tests. This changes the archive-source.sh script so that it clones the current git checkout into a temporary directory, checks out a fixed set of submodules, builds the tarball and finally removes the temporary git clone.
