mkimxboot: add a switch to force version

Add a switch to override the product and component version of the
sb file. This can usually for target like the Zen X-Fi2 where the
upader allows to drop any file named firmware.sb and prints the
version: by using a funky version the users can check they got it
right. This should not be used on the fuze+ or zenxfi3 because the
OF prevents downgrade.
Also make rbutil always zero out the option structure passed to
mkimxboot, this has already created bugs in the past.
