Bug#945840: libboost-python1.67.0 must not drop the Python 2.7 library

[Andreas Beckmann]

Hi all,

since python2.7 is back in boost-python and my shlibs patch is in, too,
I've requested a "transition" to get the binNMUs done to tighten the
boost-python dependencies: https://bugs.debian.org/948378
