    [DCOMLAUNCH] Add a DcomLaunch service stub
    
    This stub is responsible for providing the UUID seed to the kernel.
    For now, it generates a purely random seed - MAC address support
    is to be added.
    Because it's purely random seed and local the machine (not tied
    to the MAC address) it's made so that ExUuidCreate keeps returning
    RPC_NT_UUID_LOCAL_ONLY. It won't fix failing test for now.
    
    Nota: this service shouldn't exist as it. It should be implemented
    though rpcss DLL for both rpcss service (network service) and
    dcomlaunch service (local system service).
    Because rpcss is EXE based and wine-synced for now, I prefered
    stubbing a new service. This will have to be changed at some point.
