parse.y: change NODE_SCOPE's nd_loc to one of the parent NODE

This change (ad-hocly) adjusts the code range of NODE_SCOPE in
class/module definition because the same adjust is already done in
method definition.  I intend to just remove inconsistency between
class/module definition and method definition, but this kind of adjust
is dirty, so it should be fixed later (maybe in 2.6).
