Subject: bpf: update jmp32 test cases to fix range bound deduction
From: Daniel Borkmann <daniel@iogearbox.net>
[ no upstream commit ]
Since commit f2d67fec0b43 ("bpf: Undo incorrect __reg_bound_offset32 handling")
has been backported to stable, we also need to update related test cases that
started to (expectedly) fail on stable. Given the functionality has been reverted
we need to move the result to REJECT.
