Remove wmode hack for older versions of Flash on the Mac

Since two major releases of Flash (10.3 and 11) now handle QuickDraw negotiation correctly, remove the hack per the comment--it's no longer important that 10.2 and earlier are performant, since nobody should be running them.

BUG=None
TEST=The current version of Flash should continue to work normally.
