perf bpf-filter: Fix opts declaration on older libbpfs
Building perf with LIBBPF_DYNAMIC (ie not the default static linking of
libbpf with perf) is breaking as the libbpf isn't version 1.7 or newer,
where dont_enable is added to bpf_perf_event_opts.
To avoid this breakage add a compile time version check and don't
declare the variable when not present.
Fixes: 5e2ac8e8571df54d ("perf bpf-filter: Enable events manually")
