Install dynamically loadable modules into a private subdirectory

under libdir, for a cleaner separation in the installation layout
and compatibility with binary packaging standards.  Point backend's
default search location there.  The contrib modules are also
installed in the said location, giving them the benefit of the
default search path as well.  No changes in user interface
nevertheless.
