efi: mark as broken on i386

[imp]

Summary

We're never going to support EFI booting on i386 (32-bit). Start to
decommission it, since it's never worked.

Yeah. In the past I would have argued that we should work on support it (back when Intel had viable contemporary 32-bit hw and a 32-bit Tianocore to go with it) but at this point i386's future overall is not clear and we're not going to put effort into this.

With illumos loader I actually made working 32-bit loader.efi to start 64-bit kernel (on hw supporting that), but thats about how far we went as illumos did drop 32-bit kernel on x86. So it is/was basically as interesting thought game... still dead end, I'm afraid:)
