Missing category assignment in optical dvd write tests

[Marc Tardif]

This is the first line of the command for the dvd-write and dvd-write-automated tests:

cat <<'EOF' | run_templates -t -s 'udev_resource | filter_templates -w "category"'

The whitelist argument to the filter_templates script is missing an assignement. Instead, it should look something like:

cat <<'EOF' | run_templates -t -s 'udev_resource | filter_templates -w "category=CDROM"'
