ARROW-3013: [Website] Fix download links on website for tarballs, checksums

I'm not sure why the signatures are missing from:
- https://www.apache.org/dyn/closer.cgi/arrow/arrow-0.10.0/
- https://www.apache.org/dyn/closer.cgi/arrow/arrow-0.10.0/binaries

Perhaps signatures are not supposed to be distributed with `dyn` mirroring.

The new links will point to sha256 and sha512 signatures per ASF policy, see recent change https://github.com/apache/arrow/pull/2584

Apache Arrow Website

Development instructions

If you are planning to publish the website, you must first clone the arrow-site git repository:

git clone --branch=asf-site https://git-wip-us.apache.org/repos/asf/arrow-site.git asf-site

Now, with Ruby >= 2.1 installed, run:

gem install jekyll bundler
bundle install

# This imports the format Markdown documents so they will be rendered
scripts/sync_format_docs.sh

bundle exec jekyll serve

Publishing

After following the above instructions the base site/ directory, run:

JEKYLL_ENV=production bundle exec jekyll build
rsync -r build/ asf-site/
cd asf-site
git status

Now git add any new files, then commit everything, and push:

git push

Updating Code Documentation

To update the documentation, run the script ./dev/gen_apidocs.sh. This script will run the code documentation tools in a fixed environment.

C (GLib)

First, build Apache Arrow C++ and Apache Arrow GLib.

mkdir -p ../cpp/build
cd ../cpp/build
cmake .. -DCMAKE_BUILD_TYPE=debug
make
cd ../../c_glib
./autogen.sh
./configure \
  --with-arrow-cpp-build-dir=$PWD/../cpp/build \
  --with-arrow-cpp-build-type=debug \
  --enable-gtk-doc
LD_LIBRARY_PATH=$PWD/../cpp/build/debug make GTK_DOC_V_XREF=": "
rsync -r doc/reference/html/ ../site/asf-site/docs/c_glib/

Javascript

cd ../js
npm run doc
rsync -r doc/ ../site/asf-site/docs/js

Then add/commit/push from the site/asf-site git checkout.
