TT#133502 Remove using of Data::Compare module

Before the logic was - compare 2 structures and if they are different
analyze every element and exception list.
But there is no sense to do this 1st comparison as they are always
different that's why we have exception list. So remove this module.

Also add perl:Depends to dependencies.
