[STR New]

Yves-Alexis Perez reported that since 2.x, cups clients don't connect to
the correct socket: https://bugs.debian.org/792730.

I've tried to debug this, and my analysis is that since 2.x, `lpstat -H`
reports localhost:631 instead of /var/run/cups/cups.sock , even with the
socket file as follows in both 1.7 and 2.0:

srw-rw-rw- 1 root root 0 jui 18 12:36 /var/run/cups/cups.sock

I've traced this to be correctible by changing the access checks in
cups_finalize_client_conf, with the attached patch.

Does this make sense?
