selftests/bpf: Test invariants on JSLT crossing sign

Browse Source 
The improvement of the u64/s64 range refinement fixed the invariant
violation that was happening on this test for BPF_JSLT when crossing the
sign boundary.

After this patch, we have one test remaining with a known invariant
violation. It's the same test as fixed here but for 32 bits ranges.
