BTF is required for 'struct bpf_timer' to be recognized inside map value.
The bpf timers are supported inside inner maps.
Remember 'struct btf *' in inner_map_meta to make it available
to the verifier in the sequence:
struct bpf_map *inner_map = bpf_map_lookup_elem(&outer_map, ...);
if (inner_map)
timer = bpf_map_lookup_elem(&inner_map, ...);
