bin/nocss: Handy script to inhibit CSS decryption by `libdvdread'.

My DVD archive is already decrypted, so CSS is unnecessary; but
`libdvdread' still takes some time -- sometimes a long time -- trying to
`crack' the nonexistent keys, and, on rare occasions, this can actually
result in a failure to read the plain content of the DVD image.
