Bug 7088: (follow-up) AllowRenewalLimitOverride fix

This patch causes the click event listener on the #override_limit to be
created if EITHER the AllowRenewalOnHoldOverride OR
AllowRenewalLimitOverride sysprefs are enabled. Previously, it would
only be created if the AllowRenewalLimitOverride syspref was enabled,
which would cause the checkbox to be displayed but do nothing.
