2dbbdeda77("sched_ext: Fix scx_bpf_dsq_insert() backward binary compatibility") renamed the new bool-returning variant to scx_bpf_dsq_insert___v2 in the kernel. However, libbpf currently only strips ___SUFFIX on the BPF side, not on kernel symbols, so the compat wrapper couldn't match the kernel kfunc and would always fall back to the old variant even when the new one was available. Add an extra ___compat suffix as a workaround - libbpf strips one suffix on the BPF side leaving ___v2, which then matches the kernel kfunc directly. In the future when libbpf strips all suffixes on both sides, all suffixes can be dropped.
