[qemu-web RFC PATCH] _download/source.html: show the GPG fingerprint for releases

["Alex Bennée" <alex.bennee@linaro.org>]

At the moment we mention the signature but don't actually say what it
is or how to check it. Lets surface the fingerprint on the information
along with a guide of how to verify the download.
