Use git archive to create tarballs of qemu and submodules instead of
cloning the repository and the submodules.  This is a order of magnitude
faster because it doesn't fetch the submodules from the internet each
time the script runs.

Notes:
    v2: don't run git submodule update (except for uninitialized submodules)
