tdf#118639: store ODF encryption data for autorecovery
When saving autorecovery information, ODF is used. If the original
document is password-protected, its autorecovery is also generated
password-protected (since ef87ff6680f79362a431db6e7ef2f40cfc576219).
But when the stored encryption data for non-ODF document does not
contain "PackageSHA256UTF8EncryptionKey" value, following
ZipPackage::GetEncryptionKey fails, so the whole save fails.
So just generate and append ODF encryption keys where we still have
user password.
