Always get the hint directly from %^H

Since we explicitely ensure that we only fetch the hint at compile time, we
should always be able to get it from %^H. However, the require propagation
bug was fixed for %^H only in 5.12, while it was fixed in 5.10.1 for the
internal hint chain. So we also have to enable the require propagation
workaround on 5.10.1.
