    scripts/mkits.sh: Fix the hash algorithm paramter
    
    The mkits.sh script help message states hash algorithm can be
    specified using the -H command-line option, but it does not work
    currently due to a bug in the script.
    
    This patch fixes this problem by changing the option from -S to
    -H and specify getopts parameter after it
