Remove authlinkedin instead

If the publishing protocol permits MIME-based identification of content types, the content typeof the metadata instance MUST be application/samlmetadata+xml.

The old privatekey_pass was (wrongly) expected to be reused for the new
privatekey_pass. That prevented my SP from loading the new_privatekey.
Users could not log in from entities using the new key.

Clarify that the new key needs a new_privatekey_pass entry.
