kexec_file: use SHA-256 library API instead of crypto_shash API
This user of SHA-256 does not support any other algorithm, so the
crypto_shash abstraction provides no value. Just use the SHA-256 library
API instead, which is much simpler and easier to use.
Tested with '/sbin/kexec --kexec-file-syscall'.
