Check LTSS product to verify

After a non free extension has been activated successfully
on a PAYG system, RMT calls ZypperAuth verify_instance method
without any other information, the SCC verification of the activation
would fail as there is no product info to check against

Adding the product id present in the request params,
that way RMT can fetch the product class and verify properly

This Fixes bsc#1230154
