Bug 18906: Display all funds the logged in user can use

Bug 18906: Display all funds the logged in user can use

There are complex conditions to know if a librarian can use a fund, we
cannot do that with a SQL query, we need to use C4::Budgets::CanUserUseBudget

When this patch is applied then all funds are visible to both
superlibrarian patrons and patrons with all acq permissions
