fix malformed image URL and harden img rewrite

Correct a https:/// typo in the tumblr post org source that produced a
404ing cross-origin image URL. Because the extra slash meant the string
no longer matched, rewrite_img_urls() skipped it and shipped the broken
URL. Make the rewrite pattern tolerate stray slashes so a source typo
can't silently pass through un-rewritten again.

     Requires the server to serve /var/www/img/ at /img/ on the cleberg.net vhost
     (e.g. `ln -s /var/www/img /var/www/cleberg.net/img`).
+    The pattern tolerates a stray number of slashes after the scheme
+    (https:/img, https:///img, ...) so a typo in the org source can't silently
+    slip through un-rewritten and ship a broken cross-origin URL.
