suggest binNMUs for all arches: python2.[2,3]-libplot

[Nathanael Nerode <neroden@twcny.rr.com>]

python2.1-libplot
python2.2-libplot

Both need rebuilds for new C++-transitioned plotutils, but
(a) apparently don't need any source or build-depends changes
(b) don't produce C++ libraries so don't need the 'full treatment'.

The same has apparently been done already with libplot-perl, although
some arches (arm, m68k, s390, sparc) haven't uploaded yet, so I'm not
totally sure.
