Bug 23233: AllowItemsOnHoldCheckout is misnamed and does not indicate it is for SIP-based checkouts only

The system preference AllowItemsOnHoldCheckout only affects SIP based checkouts. I believe we should rename it AllowItemsOnHoldCheckoutSIP so it matches AllowItemsOnHoldCheckoutSCO. We should also update the description as well.

As far as I know AllowItemsOnHoldCheckout has never affected anything except SIP traffic. That does not preclude the addition of another AllowItemsOnHoldCheckout syspref that would affect the staff interface, but that would be an enhancement and is outside the scope of this bug report.

Test Plan:
1) Test AllowItemsOnHoldCheckout via SIP
2) Apply this patch
3) Test AllowItemsOnHoldCheckoutSIP via SIP
4) Note there is no difference!
5) Note the syspref description has been update to mention SIP
