selftests/bpf: bpf_cookie: Skip kprobe_multi tests without bpf_testmod

The kprobe_multi subtests rely on bpf_testmod fentry ksyms.

When bpf_testmod isn't available, libbpf fails to resolve
bpf_testmod_fentry_test* and skeleton load fails with -ESRCH, causing
false failures.

Skip these subtests when env.has_testmod is false.
