    gdbserver: remove unused variable
    
    When building with clang 15, I got this error:
    
      CXX    server.o
    server.cc:2985:10: error: variable 'new_argc' set but not used [-Werror,-Wunused-but-set-variable]
      int i, new_argc;
                 ^
    Remove the unused variable to eliminate the error.
    
    Tested by rebuilding on x86_64-linux with clang 15.
