    rdp-server: Run primitives benchmark when the server starts
    
    For different actions, like colour conversion, FreeRDP uses the FreeRDP
    primitives.
    When using the FreeRDP primitives the first time, FreeRDP runs a small
    benchmark.
    This benchmark can take up to ~310ms. Running the benchmark earlier
    (, when the server starts), saves that time, when the first RDP client
    connects.
    
    So, add a primitives_get() call, when the RDP server initializes to
    ensure that the benchmark won't have to run any more, when the user
    connects.
