[Buildroot] [PATCH v2] SDL_mixer: Prefer Tremor over libvorbis

When Tremor is enabled, configure SDL_mixer to use this Vorbis decoding
library instead of libvorbis. Since Tremor does fixed-point math, it is
safe to assume that if it's enabled then it is faster than libvorbis on
the target architecture.

Notes:
    v2: Remove Config.in option; enable Tremor support if Tremor is enabled
        in the config.
