Add a encode() to AnsibleVaultEncryptedUnicode (#19840)

* Add a encode() to AnsibleVaultEncryptedUnicode

Without it, calling encode() on it results in a bytestring
of the encrypted !vault-encrypted string.

ssh connection plugin triggers this if ansible_password
is from a var using !vault-encrypted. That path ends up
calling .encode() instead of using the __str__.

Fixes #19795

* Fix str.encode() errors on py2.6

py2.6 str.encode() does not take keyword arguments.
