fsverity: Switch from crypto_shash to SHA-2 library (2025-07-14 11:29:32 -0700)

----------------------------------------------------------------

Convert fsverity and apparmor to use the SHA-2 library functions instead of crypto_shash. This is simpler and also slightly faster.

----------------------------------------------------------------
Eric Biggers (3):
apparmor: use SHA-256 library API instead of crypto_shash API
fsverity: Explicitly include <linux/export.h>
fsverity: Switch from crypto_shash to SHA-2 library
