auto-t: remove requirement for /var/lib/{ead,iwd}

The host systems configuration directories for IWD/EAD were
being mounted in the virtual machine. This required that the
host create these directories before hand. Instead we can
just set up the system and IWD/EAD to use directories in /tmp
that we create when we start the VM. This avoids the need for
any host configuration.
