bpf-translate.cxx: fix build against upcoming `gcc-14` (`-Werror=calloc-transposed-args`)
    
    `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
