VtsKernelEncryptionTest: drop local fscrypt UAPI definitions

Now that Bionic's copy of <linux/fscrypt.h> has been updated, the local
definitions of FS_IOC_GET_ENCRYPTION_NONCE and
FSCRYPT_POLICY_FLAG_IV_INO_LBLK_32 are no longer needed.

Note that we cannot yet drop the definition of F2FS_IOC_SET_PIN_FILE,
since the f2fs-specific ioctls are only declared in a kernel-internal
header -- not in a UAPI header as they should be.

Test: 'atest vts_kernel_encryption_test' on Cuttlefish
