Builder.cdiSetupDevicesInSpecdefConfig(): use configured CDI dirs

Use the directories configured in containers.conf, now that
containers/common can tell us what they are, and now that it provides a
place to configure defaults for container tools, always override the
library's default set, even if it's empty.

Switch to the default CDI registry instead of the recenty-deprecated
non-global one.
