Use curl instead of wget to fetch the CNI tarball in e2e-node test

Curl is more ubiquitous than wget. For instance, the GCE centos-7 and rhel-7 image families ship curl by default, but not wget. Looking at the shell scripts under cluster/, they tend to use curl more than wget. (The ones that use wget, such as get-kube.sh, try curl first and only fallback to wget if it's not available.) Tested: by running node-e2e-test on Ubuntu, COS and CentOS.
