preset stable and try* flags for TRX2 headers

* changed addpattern.c to preset the stable and try flags used in TRXv2 images
to dupe CFE and pretend a stable image.
* changed trx.c to calculate TRXv2 CRC with stable and try flags set to 0xFF
like CFE does on startup
* fixed compile warnings in trx.c by explicit casting
