Fix some minor issues with the SYSV init and initramfs scripts.

This is some minor fixes to commits 2cac7f5
and 2a34db1.

* Make sure to alien'ate the new initramfs rpm package as well!
  The rpm package is build correctly, but alien isn't run on it to
  create the deb.
* Before copying file from COPY_FILE_LIST, make sure the DESTDIR/dir exists.
* Include /lib/udev/vdev_id file in the initrd.
* Because the initrd needs to use '/sbin/modprobe' instead of 'modprobe',
  we need to use this in load_module() as well.
  * Make sure that load_module() can be used more globaly, instead of
    calling '/sbin/modprobe' all over the place.
  * Make sure that check_module_loaded() have a parameter - module to
    check.
