Instead of using the corpus var|function_symbol_maps for symbol lookups,
let build_elf_symbol_from_reference use the symtab::lookup_symbol
method. That leads to a shorter implementation and we can drop the
indicative parameter.

	* src/abg-reader.cc (build_elf_symbol_from_reference): drop
	  last parameter indicating the lookup type and use corpus
	  symtab for the lookup
	  (build_function_decl): Adjust accordingly.
	  (build_var_decl): Likewise.
