[PATCH] bpf-translate.cxx: 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`:

    bpf-translate.cxx: In function 'bpf::BPF_Section* bpf::output_probe(BPF_Output&, program&, const std::string&, unsigned int)':
    bpf-translate.cxx:5044:39: error: 'void* calloc(size_t, size_t)' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
     5044 |   bpf_insn *buf = (bpf_insn*) calloc (sizeof(bpf_insn), ninsns);
          |                                       ^~~~~~~~~~~~~~~~
    bpf-translate.cxx:5044:39: note: earlier argument should specify number of elements, later size of each element
