net/tcl-scotty: Last change no longer needed, revert

The reason tcl-scotty was missing an rpath during the build is because
tclConfig.sh wasn't configured with it.  lang/tcl has been updated so
that tclConfig.sh adds the appropriate runpath for the system.

Remove the previously hardcoded "-rpath" to revert the package to be
the way it way.
