Add missing shape parameter to numpy methods

ChangeLog

   Closes #1410
 
+* Fix false positive for ``shape`` parameter of ``numpy.zeros_like`` method.
+
+  Closes PyCQA/pylint#5871
+
 * Set ``end_lineno`` and ``end_col_offset`` attributes to ``None`` for all nodes
   with PyPy 3.8. PyPy 3.8 assigns these attributes inconsistently which could lead
   to unexpected errors. Overwriting them with ``None`` will cause a fallback
