    How could i create fake dummy dynamic segment to activate dynamic loader and perform LD_PRELOAD command?

    You can't.

    Even if you could, getting LD_PRELOAD to preload something would still be useless: usually you want to interpose some symbols in your LD_PRELOADed library, but that requires these symbols to be unresolved in the main binary, or at least exported in its dynamic symbol table. A statically linked executable doesn't have any unresolved symbols, nor a dynamic symbol table by definition.
