Bug#976352: transition: libjsoncpp

[Gianfranco Costamagna <locutusofborg@debian.org>]

After having a look at the failures,
two of them are gone with new d-shlibs

Remaining are failing for unrelated stuff, or have patches:

kopanocore              fail (unrelated: #969297)
polybar                 fail (unrelated: #975795)
libseqlib               fail (#976414) forwarded upstream that might be easily patchable
mrpt                    fail (#976420) forwarded upstream and its already being worked on
open3d                  ok (might need one additional build deps due to new qt)
spring                  fail (#976452 with patch)
springlobby             fail (#976451 with patch)
vtk6                    fail (unrelated: #976424 with patch)

thanks
