initramfs: Don't try to populate /dev

Recent udev (>= 182) depend on devtmpfs filesystem mounted in /dev.

Images using sysvinit as /sbin/init mount /dev/ as devtmpfs from
/etc/rc.d/rc.sysinit (which happens before udevd(8) is launched).

Images using systemd as /sbin/init doesn't use rc.sysinit or similar
script run before udevd(8), and thus, require devtmpfs to be mounted
earlier.
