Subject: [PATCH stable 5.15 0/1] Revert "selftests/bpf: Add test for bpf_timer overwriting crash"

The bpf_timer overwriting crash test will cause bpf selftest build
fail on the stable 5.15 tree with:

progs/timer_crash.c:8:19: error: field has incomplete type 'struct bpf_timer'
        struct bpf_timer timer;
                         ^
/home/ubuntu/linux/tools/testing/selftests/bpf/tools/include/bpf/bpf_helper_defs.h:39:8:
note: forward declaration of 'struct bpf_timer'
struct bpf_timer;
       ^
1 error generated.

Test shows this can only be built with 5.17 and newer kernels. Let's
revert it for the 5.15 tree.
