#17562: DataDirectory permissions are too restrictive when using

Comment (by jamielinux):
I've also realised that CAP_CHOWN and CAP_FOWNER are required (or the
equivalent SELinux capabilities chown and fowner) if creating a
ControlSocket.
The parent directory for the socket (eg, /var/run/tor) must only be
writable by the default GID. However, Tor tries to create the Unix socket
before dropping root permissions and so the root user is trying to
chown/chmod files that it doesn't have access to.
What do you think about this third patch to fix this issue? It seems to
work, but I'll admit I don't know what the repercussions may be or whether
I've broken something else.
