Bug 19933: Remove patronflags - tricky ones

Here we are, patronflags is used in a couple of places where (almost) all flags
were really useful: C4::SIP::ILS::Patron->new and circulation.pl

This patch only deal with the circulation code as I am not convident
enough with SIP code.

The change does not seems trivial because of the complexity of the
existing code, but the logic is the same. We send a variable to the
template depending on the situation of the patron.

I guess only code eyes ball could catch issue in this patch quickly.

Maybe we need to find a good place in a Koha module to move this code
and provide code coverage (especially when C4::SIP::ILS::Patron will
reuse it).
