cgroup.py: fix nested loop variable in get_cgroup_mounts()

In get_cgroup_mounts(), both files '/proc/mounts' and
'<mountpoint>/cgroup.controller' uses 'line' as loop variable
to read lines from the file.  The issue here is that, they are
nested. This patch renames second loop variable
'line' -> 'ctrlf_line'.
