selftests/bpf: Fix bpf_cookie and find_vma in nested VM
bpf_cookie and find_vma are flaky in nested VMs, which is used by some CI
systems. It turns out these failures are caused by unreliable perf event
in nested VM. Fix these by:
1. Use PERF_COUNT_SW_CPU_CLOCK in find_vma;
2. Increase sample_freq in bpf_cookie.
