Andrii Nakryiko 32c7cbb75b libbpf: Fix logic for finding matching program for CO-RE relocation

[ Upstream commit 966a750932 ]

Fix the bug in bpf_object__relocate_core() which can lead to finding
invalid matching BPF program when processing CO-RE relocation. IF
matching program is not found, last encountered program will be assumed
to be correct program and thus error detection won't detect the problem.
