util/sconfig: fix check for count of command line arguments

Valid invocations are when -s|b|k outputfile is missing (argc == 3)
    and when it is followed by the file name (argc == 5); it's an error
    when "outputfile" is missing (argc == 4) or when there are more
    arguments than expected (argc > 5).
    Fixes "Uninitialized argument value" error found by scan-build from
    clang version 3.2-11.
