Fixes#8635 by adding VERSION and BUILD_NUMBER files in the correct nix
template and updating bash script in order to prevent it from failing,
due to the git repository being not initialized in the nix environment.
Move scripts/build_no.sh and scripts/gen_build_no.sh to
scripts/version/build_no.sh to prevent Nix from rebuilding when
unrelated scripts are touched.
