[rubygems/rubygems] Move default specifications dir definition out of BasicSpecification. 
This was never the right place. The method got there just by evolution,
not by design. Move it within default methods, where it suits better.

Since this method is presumably used just internally, it should be safe
to deprecate it and remove later.
