Bug 24503: fix missing use in value builder barcode_manual.pl

Bug 22721 added use C4::Biblio in cataloguing/value_builder/barcode.pl.
This is missing in value builder barcode_manual.pl.
You get the error :
Undefined subroutine &Koha::FrameworkPlugin::GetMarcFromKohaField called at cataloguing/value_builder/barcode_manual.pl line 41.

Test plan :
1) Configure a subfield of item to use value builder barcode_manual.pl
2) Go to a record
3) Try to add a new item
4) Check the value builder is OK
