Print method qualifiers.
For specializers, print class names, not class objects, and print eql specializers.

(defmethod m :around (a b (c (eql "10"))))
was

#<standard-method M (#<BUILT-IN-CLASS T> #<BUILT-IN-CLASS T>
                     #<CLOS:EQL-SPECIALIZER>)>
becomes
#<standard-method M :AROUND (T T (EQL "10"))>
