PlaySoundTest.test_alias_fallback(): Disabled this test, and explained

why in a new comment.  My home Win98SE box is one of the "real systems"
alluded to (my system "default sound" appears to have vanished sometime
in the last month, that's certainly not a Python bug, and the MS
PlaySound docs are correct in their explanation of what happens then).

Bugfix candidate.  If someone can still sneak it into 2.3.1, that would
be good.
