["CC/pkgconfig", "system_library"] Add -rpath

When a shared library is picked up from the host system via pkg-config
that is located at a non-standard location, binaries linked against
this library by a standard linker either need LD_LIBRARY_PATH set
appropriately, or -rpath set at link time. However, not all custom
installations set -rpath in the link flags in their pkg-config file.
Therefore, in order to get working binaries (and not have to set
custom paths in tests), add a -rpath for every -L option found in
the ldflags provided by pkg-config.
