Let the spec file create a kobodl system group instead of a user group.

Description of problem:
When installing Kobo Deluxe via yum a group `kobodl` is created. However the group lies outside of the range for system user accounts as defined in /etc/logins.defs, creating a potential for colliding group ids. In my case the user group id of my primary account of an fedora 17 installation with separate /home partition collides with a new installation of fedora 19, because the kobodl group was created before my user account in question.

Version-Release number of selected component (if applicable):
0.5.1-11.fc19

How reproducible:
Install KoboDeluxe and compare the kobodl gid with the limitations of /etc/login.defs

Steps to Reproduce:
1. yum install KoboDeluxe
2. Compare output of `grep kobodl /etc/group` and `grep 'SYS_GID_\(MIN\|MAX\)' /etc/login.defs`

Actual results:
The group id of kobodl lies outside of SYS_GID_MIN and SYS_GID_MAX.

Expected results:
The group id of kobodl should lie between SYS_GID_MIN and SYS_GID_MAX.

Additional info:
The packaging policies for users and groups[1] state, that the dynamic allocation for groups should use the -r flag of addgroup, which tells addgroup to create 'system groups'.

The attached unified patch implements the change in the spec file as suggested in the wiki article.
