input.conf: unmap some more obscure bindings

Changing audio-delay is probably not needed.

Changing balance "works", but not as expected (sets up a pan matrix to
change left/right contributions to each other, rather than changing the
relative volumes of each channel).

I expect that the rest are not in use by anyone.
