1-2 (u64) friend code to validate

The friend code can be derived from the textual form of "1234-5678-9012" by stripping the slashes and then converting the string to an integer.

This function just calls FRDU:PrincipalIdToFriendCode with the lower half of the friend code and checks if the checksum byte returned matches the input.
