Remove unused self checkout org unit setting

[Jeff Godin]

There are currently two similarly-named org unit settings related to requiring patron passwords before a patron can use the web based self checkout interface.

The setting named circ.selfcheck.require_patron_password is unused, and can/should be removed.

Working branch to follow.

Thanks to Lynn Floyd for pointing this out.

Adding a reminder that the org unit history tables might contain this setting if say, a library tried to use the setting not knowing which setting was redundant and unused. If there is such an entry in the settings history, the upgrade script will fail due to these leftover entries.

Already spoke with Jeff on this, but removing the pullrequest tag and assigning back to him to finish up.

I have created a signoff branch that includes the change that Ben mentioned in comment #2:

Tested everything and appears to be working as intended with the removal of the unused setting. Added a release note and pushed the whole thing to master for 2.12. Thanks Jeff and Chris!
