[PATCH bpf-next 3/4] selftests/bpf: Match the insn number of the out-of-range message

[Qiliang Yuan]

"patch list: jump pushed out of range by patches" expects the load to
fail with "insn %d cannot be patched due to 16-bit range".

It matches only the fixed part of the message. Which insn the message
names is what the patch list decides: the jump that got out of range,
not the insn that a patch replaced.

Match the whole message, with insn 2, the jump over the divisions.

Fixes: 67d4d0b73c29 ("selftests/bpf: Test jumps around patched instructions")
