Bug 7088: (follow-up) Default hold checkbox display

As per item 4 here:
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=7088#c24

Now, the checkbox for renewing on hold items behaves the same way as the
checkbox for renewing items that have reached their renew limit. It is
necessary to check the re-labelled "Override renewal restrictions"
checkbox before it is possible to select on-hold items for renewal.
