[Bug 1177408] [NEW] lxc-list crashes when passed --nesting with a running nested container

[Stéphane Graber]

Public bug reported:

== Rationale ==
lxc-list is a compatibility wrapper for lxc-ls printing a deprecation warning before showing its output.
As lxc-ls calls itself to deal with nested containers, that deprecation warning is causing invalid json to be generated and causes a crash.
The solution is to update the distro patch to only show the warning when lxc-ls isn't calling itself.

== Test case ==
1) Create a first container
2) Create a sub-container (switch to the nesting apparmor profile, install lxc in the container, create a sub-container)
3) Run: lxc-list --nesting on the host
4) lxc-list shouldn't crash anymore

== Regression potential ==
The only difference is the addition of a condition for the deprecation warning, so I'm not seeing any room for regression there.
