Fix referrer policy meta tags.

[DominikWA]

Close #14374

Hello everybody,

I have change the referrer policy in the .htaccess file in the nextcloud root. I noticed that the setting does not work because there are still meta tags that manipulate the referrer policy.

In this PR I want to remove the unnecessary meta tags from the layout files so changes at the .htaccess referrer policy will work.

Best,
Dominik

Could you rebase your branch to master and change target? Backportbot will do the backport if possible. Workflow is usually pr against master and backport to stableX

I have redone my changes based on current master and changed the target to master.

I have also removed this tag, I believe that this is totally unnecessary since there is no referrer-policy Never.
