ubuntu: Use direct udevd method to start udev on Ubuntu.

On Ubuntu, /etc/init.d/udev is a symlink to an upstart file,
but running that causes the appliance to hang.

Therefore detect if this is a symlink and fall through to the
direct start of udevd.  This shouldn't affect Debian because the
file is not a symlink on standard Debian.
