Added encryption support for zfs recv -o / -x

One small integration that was absent from b52563 was
support for zfs recv -o / -x with regards to encryption
parameters. The main use cases of this are as follows:

* Receiving an unencrypted stream as encrypted without
  needing to create a "dummy" encrypted parent so that
  encryption can be inheritted.

* Allowing users to change their keylocation on receive,
  so long as the receiving dataset is an encryption root.

* Allowing users to explicitly exclude or override the
  encryption property from an unencrypted properties stream,
  allowing it to be received as encrypted.

* Receiving a recursive heirarchy of unencrypted datasets,
  encrypting the top-level one and forcing all children to
  inherit the encryption.
