selftests/bpf: Fix also no-alu32 strobemeta selftest
commit a20eac0 upstream. Previous fix aded bpf_clamp_umax() helper use to re-validate boundaries. While that works correctly, it introduces more branches, which blows up past 1 million instructions in no-alu32 variant of strobemeta selftests. Switching len variable from u32 to u64 also fixes the issue and reduces the number of validated instructions, so use that instead. Fix this patch and bpf_clamp_umax() removed, both alu32 and no-alu32 selftests pass.
