Eliminate broken rpmps append() method from python bindings (RhBug:538218)

- The code to insert new problems has been using invalid conversion code
  causing crashes since 2004 and nobody noticed, safe to say this is an
  unused interface. Additionally the method argument flags were wrong, it
  was declared as METH_VARARGS but actually expected METH_O semantics. RIP.
