[Tails-l10n] wiki translation - German

Hi all,

I started translating some pages in the encryption_and_privacy chapter
some time ago, but didn't yet publish them.
That I want to do now and try to regularly translate the less
dynamic/frequent changing pages in the future.

My repo is
git@???:flapflap/tailsxlat.git
and my OpenPGP key can be found in the repo description
