Subject: SAGA: Use the new "Miles" drivers for AdLib and MT-32

Note that this breaks the IHNM demo, as provided on the ScummVM web
page, since it doesn't have the sample.ad and sample.opl files
needed, but I have a feeling that this is a packaging error on
our part.

I don't have the original release of ITE, so I can't test that.
