Fix more leaks

 - get_parent_pid: free buffer returned from read_line after use.
 - workspace_for_pid: ensure free_pid_workspace is called when
   pid_workspaces are removed from config->pid_workspaces.
 - cmd_split: return the cmd_results from _do_split, so that the
   parent function may free it.
