libbpf: Fix section counting logic
e_shnum does include section #0 and as such is exactly the number of ELF sections that we need to allocate memory for to use section indices as array indices. Fix the off-by-one error. This is purely accounting fix, previously we were overallocating one too many array items. But no correctness errors otherwise.
