This quirk is needed to boot macOS 10.6 (and probably older) with 32-bit
kernel in 32-bit OVMF. Similar to 64-bit mode, hibernation wake is not
compatible with this quirk.

This change also partially fixes compatibility with a few other quirks
(e.g. AvoidRuntimeDefrag), but they are not really tested.

Note: modern Xcode cannot build for macOS 10.6 even when
-mmacosx-version-min=10.6 is provided and many 10.6 targets
are 32-bit. If anyone needs to compile for this legacy, they
are really on their own.

Required due to brew adopting PEP 668

Download the big file first (BaseSystem) and then the chunklist may result in a token timeout for people with slow internet connections, to work around this simply moving the order of download so that the chunklist downloads first solves this issue.
