1. Fix DepProxy#== undefind method error …

   DepProxy#== crashed with an undefind method error
   for anything other than a DepProxy class or nil
   as parameter. This was caused that it was assumed
   only DepProxy instances or nil can get passed as
   parameter. This commit implements checking the class
   as well and returns false if the classes are not
   the same.
   
   Fixes jruby/jruby#5280 travis-ci/travis-ci#9994

2. Fix DepProxy#hash calculation …

   According to the official Ruby documentation, "the eql? method returns true if obj and other
   refer to the same hash key." This was not the case as the hash key of a DepProxy instance was
   only calculated based on the dep object but in the eql? method dep and platform attributes were
   computed. This caused that equal objects returned different hash keys.
