sys/linux: add BPF_RB_* flags for ringbuf helpers
BPF helpers bpf_ringbuf_{discard,submit,output} take a set of flags.
This commit describes those flags.
The default is a zero value, but the kernel doesn't have a macro for
that. Thus, "0" is simply added to the flag definition.
Note bpf_ringbuf_reserve also has a flags argument, but it is currently
unused on the kernel side.
