spec: Require libacl when building the QEMU driver
spec: Require libacl when building the QEMU driver

For the namespaces feature to work properly we need to be able
to make a perfect copy of the original /dev, including ACLs.

By adding a BuildRequires on libacl-devel we ensure that ACL
support will be enabled at configure time and made available
to the QEMU driver.
