gnu: python: Do not use patchelf.

* gnu/packages/python.scm (python-2): Add rpath for lib directory of output to
  LDFLAGS.  Remove 'patchelf' from inputs.  Remove #:modules and
  #:imported-modules from arguments.  Remove 'add-lib-to-runpath' phase.
  (python): Do not add #:modules to inherited package arguments.
