When compiling libbpf with some compilers, this warning is triggered:

libbpf.c: In function ‘bpf_object__gen_loader’:
libbpf.c:9209:28: error: ‘calloc’ sizes specified with ‘sizeof’ in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
9209 | gen = calloc(sizeof(*gen), 1);
| ^
libbpf.c:9209:28: note: earlier argument should specify number of elements, later size of each element

Fix this by inverting the calloc() arguments.
