Scott Graham 0567536f86 win: Attempt to fix unloaded modules list by using RtlGetUnloadEventTraceEx
I haven't been able to reproduce this locally, but we see errors in
crash dumps where the unloaded module list consists of a number of
modules with invalid names and implausible addresses. My assumption is
that RTL_UNLOAD_EVENT_TRACE isn't correct for some OS levels. Instead of
trying to finesse and test that, use RtlGetUnloadEventTraceEx() instead
of RtlGetUnloadEventTrace(), which returns an element size. (This
function is Vista+ which is why it wasn't used the first time around.)
