ctracer: Initialize the 'parm_list' variable, detected by covscan 

It may be used uninitialized, fix it.

  Error: UNINIT (CWE-457):
  dwarves-1.21/ctracer.c:401: var_decl: Declaring variable "parm_list" without initializer.
  dwarves-1.21/ctracer.c:470: uninit_use_in_call: Using uninitialized value "*parm_list" as argument to "%s" when calling "fprintf". [Note: The source code implementation of the function has been overridden by a builtin model.]
