    linux(4): Move use_real_names knob to the linux.c
    
    MI linux.[c|h] are the module independent in terms of the Linux emulation
    layer (ie, intended for both ISA - 32 & 64 bit), analogue of MD linux.h.
    There must be a code here that cannot be placed into the corresponding by
    common sense MI source and header files, i.e., code is machine independent,
    but ISA dependent.
    For the use_real_names knob, the code must be placed into the
    linux_socket.[c|h], however linux_socket is ISA dependent.
