libbpf: Allow specifying 64-bit integers in map BTF.
__uint() macro that is used to specify map attributes like:
__uint(type, BPF_MAP_TYPE_ARRAY);
__uint(map_flags, BPF_F_MMAPABLE);
It is limited to 32-bit, since BTF_KIND_ARRAY has u32 "number of elements"
field in "struct btf_array".
Introduce __ulong() macro that allows specifying values bigger than 32-bit.
In map definition "map_extra" is the only u64 field, so far.
