Fix mailing list subscription for digests

The proper way to subscribe to e.g. internals digest is sending a mail
to `internals+subscribe-digest@`, but not `internals-digest+subscribe@`.

Since `$_POST['maillist']` contains `internals-digest` in this case, we
apply a simple regex to catch that, and assemble the proper email
address in the following.

Changed paths:
  M  public/entry/subscribe.php
