[lltx] unicode-math breakage with newest TL '10 update

[ulrik.vieth at arcor.de]

I've tried manually undoing the change in luaotfload, but it didn't help,
so I'm no longer sure about my attribution of the problem to luaotfload.

It could equally well be caused by some other recent updates in TL,
such as fontspec, unicode-math or expl3.  Will, could you check?

Regards, Ulrik
