Embed the IPFire background image into the redirect template directly via CSS instead of loading it from somewhere else. This is necessary because of Content Security Policy (CSP).
This patch inserts the base64 encoded image during build so nothing needs to be updated twice in case background image changes.
It supersedes first, second and third version of this patch and has been successfully tested during a clean build.
Fixes #11650
