This is sometime used to avoid circular dependencies between libxxx and
libxxx-bin packages, when a library can exec a binary in /usr/lib linked with itself.
Since libxxx-bin binaries are always exec-ed by libxxx, there is no
need for them to depend on libxxx, while libxxx needs to depend on
libxxx-bin.
Demoting the shlibs:Depends prevent the otherwise circular dependency.
