plugin-runner: Fix minor memory leak

* plugin-runner.c (free_plugin): Even if argv[0] is NULL, as for the
                                 pseudo-plugin for global options,
                                 free all other arguments by simply
                                 starting at argv[1] and freeing
                                 plugin_node->name (which is always
                                 argv[0]) separately.
