Non-root backends should use CUPS_DEFAULT_GROUP

In CUPS 1.2rc1 I see that the parallel backend no longer runs as
root. The defaults seem to be user lp and group nobody (although
'CUPS_DEFAULT_GROUP' is "lp" in my config.h).

This means that the parallel backend doesn't have permission to open
this device for reading:

crw-rw---- 1 root lp 6, 0 Mar 29 08:52 /dev/lp0

Shouldn't CUPS_DEFAULT_GROUP be used instead of "nobody" here?:

scheduler/conf.c:
340 /*
341 * Find the default group (nobody)...
342 */
343
344 group = getgrnam("nobody");
345 endgrent();

Reset to priority 2; this is just a default setting issue (adding "Group lp" fixes things with the current release candidate)
