Subject: [PATCH] macos: just build chainloader entries, don't try any xnu xnu.

Since our bugs tell us that the xnu boot entries really just don't work
most of the time, and they create piles of extra boot entries, because
they can't quite figure out 32-vs-64 and other stuff like that.

It's rediculous, and we should just boot their bootloader through the
chainloader instead.

So this patch does that.

Resolves: rhbz#893179
