  ubifs: wire up FS_IOC_GET_ENCRYPTION_NONCE (2020-03-19 21:57:06 -0700)

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

Add an ioctl FS_IOC_GET_ENCRYPTION_NONCE which retrieves a file's
encryption nonce.  This makes it easier to write automated tests which
verify that fscrypt is doing the encryption correctly.
