[MIR] flask-script and libjsoncpp (b-d's for net-cpp)

[Matthias Klose (doko)]

these two packages show up as component mismatches, and net-cpp is bypassing the ubuntu buildability rules, in that the CI train seems to ignore main/universe build dependencies.

[Matthias Klose (doko)]

see #1218220 for libjsoncpp, please re-evaluate if this is needed.

I try to build net-cpp in xenial and have the following problem.

libjsoncpp-dev:
  Installed: 1.7.2-1
  Candidate: 1.7.2-1
  Version table:
 *** 1.7.2-1 500
        500 http://us.archive.ubuntu.com/ubuntu xenial/main amd64 Packages
        100 /var/lib/dpkg/status

However rebuilding libjsoncpp from source solves this problem.
Please have a check.
