Remove symlink to audio_effects_conf.xsd

A change is being made so that sandboxed actions need to add a
dependency on the targets of the symlinks they use. All xsd_config
modules use sandboxing by default.

In this case, the symlink isn't necessary, and we can just depend
on the audio_effects_conf_V2_0 genrule instead.
