modprobe.d: use $TMP_MOUNT_PATH

Browse Source 
The hook inside extra-data.d runs outside the chroot when
building the image which means that we need to prefix paths
inside the hook to avoid running things on the host.

We also run it with sudo because if we're running DIB not
as root, /etc is uid 0 and we'll get a permission denied.
