Eduard Zingerman 9ea8fb379f libbpf: Verify that arena map exists when adding arena relocations ...

[ Upstream commit 42be23e8f2 ]

Fuzzer reported a memory access error in bpf_program__record_reloc()
that happens when:
- ".addr_space.1" section exists
- there is a relocation referencing this section
- there are no arena maps defined in BTF.

Sanity checks for maps existence are already present in
bpf_program__record_reloc(), hence this commit adds another one.
