Retrieve Windows sound driver versions on Vista+

[historic_bruno]

Currently this is broken, as the following comment in wsnd.cpp explains:

// unfortunately this fails with Vista's DS emulation - it returns some
// GUID crap as the module name. to avoidc crashing when attempting to get
// the version info for that bogus driver path, we'll skip this code there.
// (delay-loading dsound.dll eliminates any overhead)

This may be useful info to report for debugging the new sound system.

It seems that doing DirectSoundEnumerate to get a module name is a dead-end for anything higher than XP.

This was addressed by r19877, and the code that used to be skipped is now deleted.
