selftests/bpf: Make bpf_user_ringbuf_drain() selftest callback return 1



In commit 1bfe26fb ("bpf: Add verifier support for custom callback
return range"), the verifier was updated to require callbacks to BPF
helpers to explicitly specify the range of values that can be returned.
bpf_user_ringbuf_drain() was merged after this in commit 20571567
("bpf: Add bpf_user_ringbuf_drain() helper"), and this change in default
behavior was missed. This patch updates the BPF_MAP_TYPE_USER_RINGBUF
selftests to also return 1 from a bpf_user_ringbuf_drain() callback so
as to properly test this going forward.
