    [SETUPLIB] Add two hacks in partlist.c for temporarily setting consistently the disk
partition style.
    
    Add two hacks in UpdateDiskLayout() and WritePartitions() so that the
    disk partition style is consistently set to a known value MBR, especially
    when that disk was previously new and uninitialized (RAW).
    A proper fix will be developed later when support for GPT is added.
