sbuild: how to add extra repositories

[cpaelzer]

I used to use sbuild-launchpad-chroot but without it (as outlined in these docs) we should state how one could add proposed. There are many ways to do so, this follows a recent discussion 1 on ubuntu-devel.

Hmm, if users didn't mess with mk-sbuild then proposed is default enabled (--skip-proposed) maybe using a PPA is a better example to show? Any non individual PPAs to suggest to use for this?

I've chosen to:

• add the three most common examples that came to my mind
• mention the default of mk-sbuild
• show the example with other arches that was discussed on the devel post
• keep the PPA example anonymous by using $lpuser $ppaname

Together that should make it pretty complete

Turns out this is more stupid than it should be, since we default pin proposed to not be used the above will not be sufficient.

Realizing this is more tricky I think we need to discuss what we want the official way in the packaging guide to be - and I'm unsure if my hacky way to overcome it would be the one we want - hence I filed #153 to track that.
