Introduce __COMPAT_scx_bpf_events() to use scx_bpf_events() in a
compatible way also with kernels that don't provide this kfunc.
This also fixes the following error with scx_qmap when running on a
kernel that does not provide scx_bpf_events():
; scx_bpf_events(&events, sizeof(events)); @ scx_qmap.bpf.c:777
318: (b7) r2 = 72 ; R2_w=72 async_cb
319: <invalid kfunc call>
kfunc 'scx_bpf_events' is referenced but wasn't resolved
Fixes: 9865f31d85 ("sched_ext: Add scx_bpf_events() and scx_read_event() for BPF schedulers")
