apache2: Allow downloads in openvpn and backups with latest browsers
Closes: #2002.

Entire FreedomBox UI is served within a sandbox that is originally meant for
cross-site iframes.

A newly introduced flag allow-downloads is required to trigger downloads. Two
instances where this is used in FreedomBox is openvpn profiled download and
backup download. Firefox 81 and Chrome 83 implement this flag.

Add 'allow-downloads' to sandbox directives to fix this.
