We don't package the *.so symlinks for the libraries of multipath tools. This
causes external tools trying to link against e.g. libmpathcmd.so to fail.

Open question 1: should we ship libmultipath.so? If we do, we'd also need to
ship the header files for libmultipath, which we currently don't (we only ship
header files for libmpathcmd, libmpathpersist, and libdmmp).

Open question 2: for strict compliance with 
https://en.opensuse.org/User:Mvyskocil/Shared_library_packaging_policy, 
we'd have to create subpackages libpathpersist0, libmpathcmd0. Is that required
or even reasonable?
