openzwave: Avoid picking host libraries

cpp/examples/MinOZW/Makefile contains this rule:

LIBS =  $(wildcard $(LIBDIR)/*.so $(LIBDIR)/*.dylib $(top_builddir)/*.so
$(top_builddir)/*.dylib $(top_builddir)/cpp/build/*.so
$(top_builddir)/cpp/build/*.dylib )
LIBSDIR = $(abspath $(dir $(firstword $(LIBS))))

with LIBDIR not being defined anywhere we end up picking up host
libraries.
