Remove wget usage from install-sysroot.py

CL https://codereview.chromium.org/2398633004/ used wget instead of
curl to download the sysroots because it was more standard.  However,
not even wget is bundled with some freshly-installed distros, so just
use python's urllib to download the sysroot tarballs directly.

This commit breaks people behind proxies for example us at Intel. Despite we set
the http_proxy and https_proxy env variable on Linux it fails to download the
toolchain.

Proposed fix : https://codereview.chromium.org/2554753005
