use lookup_keyword() for qualifiers

When handling qualifiers, the corresponding symbol is looked-up with
lookup_symbol() then it's checked if the symbol's type is SYM_KEYWORD.

But, only if the identifier is a keyword (struct ident::keyword) can
the symbol be a SYM_KEYWORD. Thus, non-keyword can be filtered-out
early by using lookup_keyword().

So change the call to lookup_symbol() by a call to lookup_keyword().
