[PATCH] staprun: fix build against upcoming `gcc-14` (`-Werror=calloc-transposed-args`)

[Sergei Trofimovich <slyich@gmail.com>]

`gcc-14` added a new `-Wcalloc-transposed-args` warning recently. It
detected minor infelicity in `calloc()` API usage in `systemtap`:

    staprun.c: In function 'main':
    staprun.c:550:50: error: 'calloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
      550 |                 char ** new_argv = calloc(sizeof(char *),argc+2);
          |                                                  ^~~~
