ALSA: fireworks/bebob/oxfw/dice: enable to make as built-in

commit df4833886f91eea0d20e6e97066adab308625ef8 upstream.

When committed to upstream, these four modules had wrong entries for
Makefile. This forces them to be loadable modules even if they're set
as built-in.

This commit fixes this bug.
