Fix ownership of config and state directories

Fix ownership of config and state directories

The recent RPM package restructing introduced some problems with
the ownership of /etc/ipsilon and /var/lib/ipsilon.  These were
previously owned by the 'ipsilon' user, but the changes resulted
in the ownership being set as root since the 'ipsilon' user was
not yet created when the directories were installed.

While discussing this problem, it was determined that we should
have the ownership of these directories be root, but allow other
users to traverse through them so they can access subdirectories
that they have permissions on.
