Update machine local.conf fragment numbering

Update machine local.conf fragment numbering

Lower numbering of the local.conf fragments in the machine templates
so they will be guaranteed to be before feature added fragments as
opposed to mixed in with them.  This allows referring to MACHINE in
feature fragments in a stable fashion, and makes the generated
local.conf a bit more readable.
