Don't define OpenAL redirect macros with the IDE's parser

At least with KDevelop4, macros like this interefere with contextual info by
causing it to show information about the macro itself (where it's defined and
what it defines to), rather than the function (parameters, comments, etc). It
also gets in the way of auto-completion.
