Remove dependency on libdpkg

API of libdpkg is unstable and its usage is discouraged
for purposes other than internal.
It also prevents building libaktualizr as a shared library.
As getInstalledPackages() functionality of debian package
manager seems to be unused, we will avoid reimplementing it for now.
