[PATCH 2/2] run Tor under dedicated user

["Peter Müller" <peter.mueller@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 2271 bytes --]

This allows more-fine granular firewall rules (see first patch for
further information). Further, it prevents other services running as
"nobody" (Apache, ...) from reading Tor relay keys.

Fixes #11779.
