Tweak CRC input to be backwards compatabile with ksng.
Except for torture tests, we never really used the hideously complex multi-block capabilities of the ksng version of the flash keystore, among other reasons because the only keys large enough to trigger the multi-block code were slow enough to constitute torture on their own. So we can preserve backwards compatabliity simply by including the former *chunk fields (renamed legacy* here) in the CRC and checking for the expected single-block key values. We probably want to include everything in the CRC in any case except when there's an explicit reason omit something, so, this is cheap, just a bit obscure. At some point in the future we can phase out support for the backwards compatible values, but there's no particular hurry about it unless we want to reuse those fields for some other purpose.
