MF20 [rev 19794]: Fixed two packaging errors for OpenAL and ALUT:

   1. Check C:\WINDOWS\SysWOW64 for OpenAL32.dll since that's where it ends
      up on 64-bit Windows.
   2. Reference the correct variable when installing alut.dll (in the case
      when ALUT is installed separately from OpenAL).
