cgmanager: several fixes
These all fix various ways that cgroup actions could fail if an
unprivileged user's cgroup paths were not all the same for all
controllers.
1. in cgm_{g,s}et, use the right controller, not the first in the list,
to get the cgroup path.
2. when we pass 'all' to cgmanager for a ${METHOD}_abs, make sure that all
cgroup paths are the same. That isn't necessary for methods not
taking an absolute path, so split up the former
cgm_supports_multiple_controllers() function into two booleans, one
telling whether cgm supports it, and another telling us whether
cgm supports it AND all controller cgroup paths are the same.
3. separately, do_cgm_enter with abs=true couldn't work if all
cgroup paths were not the same. So just ditch that helper and
call lxc_cgmanager_enter() where needed, because the special
cases would be more complicated.
