Alright, with this new installer backend, things got much better.

In a DUP with 114 updates, tranfiletrigger(in|postun) is invoked only once (and
I think that in my previous test I messed up the transfiletriggerpostun
scriptlet, thus it didn't run).

And I saw that, apparently, Zypper is converting filetriggers to triggers. I'm
going to keep an eye on the next DUPs.
