[Tails-l10n] [review](de) doc/about/fingerprint page

Hi,

Please review
https://gitorious.org/flapflap/tailsxlat.git
branch de-fingerprint

Commits:
c24f5d4 minor fix
120c867 translate remaining strings

On the fingerprint page, some strings were updated (often "Tails vs.
TBB" -> "Tor Browser in Tails vs. Tor Browser on other systems") in the
English version.
This branch updates the German translation accordingly.
