overlayfs: Disable renaming of network interfaces

Current qemurunner implementation expects internal network interface to
be eth0, but by default systemd renames network interfaces to have
predictable names. This causes a race in the evaluation of results of
susequent commands in case when qemurunner tries to setup the network
after the interface was already renamed and fails to do that (because
there's no eth0 interface present anymore).
