Bug 25761: Implementation of too_many_overdue has unintended consequences

Bug 24449 implemented the too_many_overdue SIP flag ( position 6 of the
patron status flags ). This has had unintended consequences as
many library use SIP2 for validation to eresource vendors ( Overdrive,
Hoopla, etc ), but do not want overdue checkouts to block the
use of these resources.

Test Plan:
1) Apply this patch
2) Restart all the things!
3) Find a patron with overdue items
4) Run a SIP2 patron information request
5) Note the "too many overdue" flag is set
6) Set the new SIP config option "disable_too_many_overdue" for the
account you used for testing
7) Restart the SIP server
8) Run the same patron information request
9) Notice the "too many overdue" flag is no longer set!
