libbpf: Forward-declare bpf_stats_type for systems with outdated UAPI headers
Systems that doesn't yet have the very latest linux/bpf.h header, enum
bpf_stats_type will be undefined, causing compilation warnings. Prevents this
by forward-declaring enum.
Fixes: 0bee106716cf ("libbpf: Add support for command BPF_ENABLE_STATS")
