Bug 24159: Set days_mode according to circ rules in 3 other places

There are 3 other occurrences where the new circ rule can be used:
 * C4::Circulation::checkHighHolds
 * Koha::Hold->set_waiting
 * misc/cronjobs/thirdparty/TalkingTech_itiva_outbound.pl

Test plan:
* checkHighHolds
Enable decreaseLoanHighHolds and fill decreaseLoanHighHoldsDuration
Setup things to hit a "high demand" alert with a shortened due date
Check an item out
=> The due date must be recalculated depending on the circ rule useDaysMode.

* set_waiting
Set ExcludeHolidaysFromMaxPickUpDelay to "1" (note that there is currently
a bug in the description of the syspref, see bug 22381 comment 19)
Mark a hold waiting
The expiration date should have been set depending on the value of the
circ rule.

* TalkingTech cronjob
Cannot test this
