Two of the BPF selftests hardcode the path to /sys/kernel/btf/vmlinux. The kernel image could potentially exist at a different location. libbpf_find_kernel_btf(), as introduced by commit fb2426ad00b1 ("libbpf: Expose bpf_find_kernel_btf as a LIBBPF_API"), knows about said locations. This change switches these two tests over to using this function instead, making the tests more likely to be runnable when /sys/kernel/btf/vmlinux may not be present and setting better precedent.
