Prevent dependencies on Debianized packages

Call dpkg-shlibdeps with arguments excluding the Debianized packages
lib{uutil1,nvpair1,zfs2,zpool2}linux from the auto-generated
dependencies of generated .debs. A shim dh_shlibdeps that calls the
real dh_shlibdeps with corresponding arguments is installed into a
temporary directory, which is in turn pre-pended to the PATH for the
alien call, working around alien's inability to directly alter the
dependencies of its output debs. Resolves #6106.
