[PATCH 6.17 069/371] perf bpf-filter: Fix opts declaration on older libbpfs

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ian Rogers <irogers@google.com>

[ Upstream commit 3a0f56d72a7575f03187a85b7869c76a862b40ab ]

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")
