Revert "Use the new net.ifnames kernel command line flag to disable p…

…ersistent interface names" As @edolstra pointed out, this behavior is not equivalent to what we had before as the kernel command line parameter won't take effect until the next boot. Probably it's not likely that someone will make this change and then add a network card before rebooting, but might as well support that since we can. This reverts commit f756369.
