Ensure configdrive isn't mounted in CoreOS ramdisks

Temporary workaround for bug #1433812. CoreOS processes the
cloud-config.yml too late the boot process to prevent mounting and
processing the configdrive. Pass coreos.configdrive=0 on the kernel
command line to ensure this doesn't occur, as it can be a security risk
(previous tenants may have written a malicious configdrive, and it would
be read before being cleaned).

Long-term, we should remove this workaround and either completely remove
the mount units from the ramdisk during the build process or get a
better fix from upstream (https://github.com/coreos/bugs/issues/314).
