tex-babel-german: update to 2.11

This release fixes an old hyphenation regression which was introduced
with babel 3.7 (16 years ago!) in a number of shorthands: Since then,
\allowhyphens is deactivated in T1 encoding. Thus, hyphenation did not
work as intended in T1 with shorthands that used \allowhyphens.
As a fix, babel-german now uses \bbl at allowhyphens which is synonymous
to \allowhyphens, except that it works in T1, in these shorthands.

Affected by this change: "a "o "u "A "O "U "f \ 
"| shorthands, and the \ck macro.

Note that this change might affect line/page breaking. But then, the
unnoticed regression fixed here did so as well.
This change also restitutes compatibility with [n]german.sty for the
mentioned shorthands.
