attribs: Add missing auto_diagnostic_group 3 times

In these spots, the error/error_at has some inform afterwards which are
explanation part of the same diagnostics, so should be tied with
auto_diagnostic_group with it.

2022-10-04  Jakub Jelinek  <jakub@redhat.com>

	* attribs.cc (handle_ignored_attributes_option, decl_attributes,
	common_function_versions): Use auto_diagnostic_group.
