genksyms: reduce type_qualifier directly to decl_specifier

A type_qualifier (const, volatile, etc.) is not a type_specifier.

According to K&R [1], a type-qualifier should be directly reduced to
a declaration-specifier.

  <declaration-specifier> ::= <storage-class-specifier>
                            | <type-specifier>
                            | <type-qualifier>
