Daniel Borkmann 316930d06b selftests/bpf: Add more ring buffer test coverage

Add test coverage for reservations beyond the ring buffer size in order
to validate that bpf_ringbuf_reserve() rejects the request with NULL, all
other ring buffer tests keep passing as well:

  # ./vmtest.sh -- ./test_progs -t ringbuf
  [...]
  ./test_progs -t ringbuf
  [    1.165434] bpf_testmod: loading out-of-tree module taints kernel.
  [    1.165825] bpf_testmod: module verification failed: signature and/or required key missing - tainting kernel
  [    1.284001] tsc: Refined TSC clocksource calibration: 3407.982 MHz
  [    1.286871] clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x311fc34e357, max_idle_ns: 440795379773 ns
  [    1.289555] clocksource: Switched to clocksource tsc
