Bug 34058: Preparation: buildPatronSearchQuery

Add table_prefix argument to buildPatronSearchQuery.
This allows the buildPatronSearchQuery function to also perform the search
on a related table, instead of the default patron table.
This is relevant because the query will be performed on the ILL API endpoint,
so the table being searched will have to be prefixed with 'patron.', instead of the
default 'me.'
