Andrii Nakryiko f7a2ccc00a libbpf: Fix realloc usage in bpf_core_find_cands ...

commit 35b9211c0a upstream.

Fix bug requesting invalid size of reallocated array when constructing CO-RE
relocation candidate list. This can cause problems if there are many potential
candidates and a very fine-grained memory allocator bucket sizes are used.
