Some documentation fixes + link to my Docker/LXC guide

I added a link to my guide about using docker containers + LXC (I am planning to maintain this at work
for future bitcoin versions), then I mentioned other virtualization options (KVM, LXC).
This commit includes a fix issue for documentation issue #4269 that consists in telling users to
checkout correct bitcoin version before using the gitian descriptors (otherwise all hell can break loose).
Also, I replaced URL for Debian 7.4 ISO with a correct one and added link to official Debian ISO sources.

Preparing the Gitian builder host
---------------------------------
The first step is to prepare the host environment that will be used to perform the Gitian builds.
In this guide it is explained how to set up the environment, and how to get the builds started.
Debian Linux was chosen as the host distribution because it has a lightweight install (in contrast to Ubuntu) and is readily available.
Any kind of virtualization can be used, for example:
- [VirtualBox](https://www.virtualbox.org/), covered by this guide
- [KVM](http://www.linux-kvm.org/page/Main_Page)
- [LXC](https://linuxcontainers.org/), see also [Gitian host docker container](https://github.com/gdm85/tenku/tree/master/docker/gitian-bitcoin-host/README.md).
You can also install on actual hardware instead of using virtualization.
Create a new VirtualBox VM
---------------------------
The first step is to create a new Virtual Machine, which will be explained in
this section. This VM will be used to do the Gitian builds. In this guide it
will be explained how to set up the environment, and how to get the builds
started.
Debian Linux was chosen as the host distribution because it has a lightweight install (in
contrast to Ubuntu) and is readily available. We here show the steps for
VirtualBox [1], but any kind of virtualization can be used. You can also install
on actual hardware instead of using a VM, in this case you can skip this section.

Uploading signatures
---------------------
After building and signing you can push your signatures (both the `.assert` and
`.assert.sig` files) to the
[bitcoin/gitian.sigs](https://github.com/bitcoin/gitian.sigs/) repository, or
if not possible create a pull request. You can also mail the files to me
(laanwj@gmail.com) and I'll commit them.
