libbpf: Fix type compatibility check copy-paste error
Fix copy-paste error in types compatibility check. Local type is accidentally
used instead of target type for the very first type check strictness check.
This can result in potentially less strict candidate comparison. Fix the
error.
Fixes: 3fc32f40c402 ("libbpf: Implement type-based CO-RE relocations support")
