please stop the dh_makeshlibs -V madness

[Sam Hocevar <sam@zoy.org>]

   Blindly using dh_makeshlibs -V in packages is preventing hundreds of
packages from entering testing. Consider this scenario:

   - package foobar, which uses libquux, is uploaded to sid.
   - 10 days pass, but foobar still did not enter testing because one of
     the autobuilders was a bit behind.
   - a new libquux is uploaded to unstable.
   - foobar gets built on the last architecture.

   If libquux uses dh_makeshlibs -V, foobar needs to wait another 10
days to enter testing! This is simply not acceptable, no change to
a library (except a rather bad packaging error, or a very specific
library) should justify the use of the -V flag without an argument.

   I am really FED UP with having to wait MONTHS until packages with
zero bugs enter testing because of this carelessness.
