aarch64: Recognize SHT_AARCH64_ATTRIBUTES

Recognize SHT_AARCH64_ATTRIBUTES. This is enough to stop elflint
complaining about unknown section types. But doesn't implement parsing
the attributes.

	* backends/aarch64_symbol.c (aarch64_section_type_name):
 	New function.
	* backends/aarch64_init.c (aarch64_init): Hook
        section_type_name.
