Fix-committed: #11372

Fix-committed: #11802

Will-fix: #11802

It actually doesn't seem to be necessary to suppress the annoying
"first run" prompt, but let's do it any way for consistency.

For the Tails 2.6 release, where we did a last minute bump of the
'debian' snapshot, some firmwares have suddenly been removed from
Debian Sid:

* firmware-amd-graphics
* firmware-intel-sound
* firmware-misc-nonfree

resulting in Tails not building any more.

Otherwise we'll have to wait for the bug and security fixes it has for
three months, until Tails 2.8. The one week delay of Tails 2.6 opened
the possibility for us to do this, so let's take the chance!

Presumably that's a page that we _really_ want to see translated.
