fix(webmention-sender): drop internal URL rewriting, fetch public URL directly

Browse Source 
The public URL (blog.giersig.eu) is reachable from inside the jail, so
the INTERNAL_FETCH_URL rewriting approach was unnecessary and caused 400/502
errors because 10.100.0.10 does not serve the static blog pages.

Simplify the livefetch patch to fetch postUrl directly.
