Add apt-pinning for deb-multimedia.org packages

[ghost]

In order to improve our control about packages from deb-multimedia repository, we should increase priority of needed packages (eg: vlc, codecs) and decrease the global repository priority.

[boyska]

next step: understand what deb-multimedia is really important for.
Build a new image without it and understand what we are really lacking.

I checked all of them, and here is the result: most of those libraries
are in jessie, too. Some of them are with a different (often more
recent) version. Some are missing. These packages are missing

libaacplus2

Know nothing about it. What is it for? Is it important?

libdvdcss2

This is for css-protected DVD. Is it that much important?

w32codecs

according to debian wiki[1], the codecs contained here are not very useful.

gstreamer0.10-ffmpeg

odd: this is in wheezy and in sid, but not in jessie nor stretch

libx264-124 142 available
libx264-132 142 available
libswscale2 3 available
libvlccore5 8 available
libavutil51 54 available
libavformat53 54 available
libavformat54 54 available
libavcodec54 54 available
libavcodec53 56 available

This is missing, too, but it is pointless:

deb-multimedia-keyring

So we could:

• drop deb-multimedia entirely, and check that most use cases are still
  satisfied
• pin just the very specific packages that we need from that repository;
  this solution will make freepto stick closer to debian, but from the
  security point of view there is just no improvement from the current
  status

I like this option.
Let's build freepto without this repository.
