Bug 31222: Reduce query size for batchMod

Bug 31222: Reduce query size for batchMod

The object search is currently:
Koha::Items->search({ barcode => \@contentlist }

Which generate code like:
barcode = 1 OR barcode = 2 OR barcode = 3 ....

This can get quite large

We can reduce the query size by using -in:
Koha::Items->search({ barcode => { -in => \@contentlist } }

Which generates code like:
barcode in ( 1, 2, 3 )

To test:
1 - Apply patch
2 - Perform batch modifications
3 - Confirm nothing has changed
