unix: add new fscrypt declarations from Linux v5.4

Create Go bindings for the updated fscrypt UAPI from Linux v5.4:

- Various new ioctls.  We use the regex FS_IOC_.*ENCRYPTION to match
  both the new and existing fscrypt ioctls.

- Various new structures for passing to the ioctls

- Various new constants named like FSCRYPT_*

- FscryptPolicy was renamed to FscryptPolicyV1.  (But the old name is
  still available for source compatibility.)

- The existing fscrypt-related constants named like FS_* (besides the
  ioctls) were renamed to FSCRYPT_*.  (But the old names are still
  available for source compatibility.)

For reference, see fscrypt.h:

Fixes golang/go#35856
