perf test shell record_bpf_filter: Skip 6.2 kernel
The BPF sample filtering requires two kernel changes below:
* bpf_cast_to_kernel_ctx() kfunc (added in v6.2)
* setting perf_sample_data->sample_flags (finished in v6.3)
The perf tools can check bpf_cast_to_kernel_ctx() easily so it can
refuse BPF filters on those old kernels (v6.1 and earlier).
But checking sample_flags appears to be difficult so current code won't
work on v6.2 kernel. That's unfortunate but I don't know what's the
correct way to handle it.
For now, let's skip v6.2 kernels explicitly (if failed) in the test.
Fixes: 9575ecdd198a50e9 ("perf test: Add perf record sample filtering test")
