LU-6387 build: lustre-dev debain package missing shared libraries

While testing on our Ubuntu platform I discovered several tools
didn't work due to missing shared libraries from lustre. This
was due to the build system packaging only the static libraries.
This patch ensure that dynamic libraries are packaged as well.
