[libvirt] [PATCH 2/4] configure: Make ACL mandatory when building the QEMU driver



When we're building a private /dev for the isolated QEMU
process, we want to be able to replicate the contents of
the original /dev as closely as possible, including ACLs.

To ensure that's always possible, make ACL support mandatory
when the QEMU driver is enabled.
