py-cffi: set LDSHARED env so that rpath is set

Browse Source 
py-cffi's .so was being built without the rpath being set.  distutils
looks at the LDSHARED for which compiler to use to build the final .so.
Since it was not set, distutils fell back to the system provided
compiler.  Setting it forces the shared library to be compiled with the
spack compiler (meaning that the rpath is set correctly).
