  Hello,

For now, the BTF nodes BTF_KIND_DECL_TAG, BTF_KIND_DATASEC, and
BTF_KIND_UNKN are ignored by libabigail, in practice.  We should thus
not abort when we encounter them.  Fixed thus.  Many thanks to Cestmir
Kalina for reporting this.

	* src/abg-btf-reader.cc (build_ir_node_from_btf_type): Ignore and
	return nil for node of kind BTF_KIND_DECL_TAG, BTF_KIND_DATASEC,
	and BTF_KIND_UNKN.  For all other nodes, abort.
