File initd_cgconfig-read-correctly-defaultcgroup.patch of Package libcgroup

From: Robert Milasan <rmilasan@suse.com>
Subject: fix defaultcgroup detection

b55ce704 (scripts: cgconfig, cleanup) introduced a regression because
read is now executed in a subshell so the variables are not visible
in the outer context and so defaultcgtoup is never non-empty.

Fix the issue by using here text which doesn't involve subshell.
