    [NTOS] Configuration Manager fixes.
    
    - Rework CmpSetSystemValues() and remove its 1st-stage text-mode setup hack, since a
real registry hive will be used for 1st-stage either.
    - Lock, then unlock the registry in NtInitializeRegistry when initializing the hives
& flusher.
    - Call CmpInitializeHiveList() (i.e., initialize the other hives like \Software,
\User, \.Default) only when we are not in setup-mode.
