lxc: bug fixes from upstream

Adding a couple of upstream fixes for lxc:
- follow symlinks when determining if Busybox is statically linked
- don't fail for lxc.network.type = none
- don't fail if no default macvlan mode is specified

More details are available in the individual patches.

+Subject: [PATCH] config_network_type: set macvlan default mode to private
+
+If a default mode is not set, the container requires an explicit
+mode specified in the config file, otherwise creating the
+container fails.

+Subject: [PATCH] network.c: Add missing LXC_NET_NONE option + refactor
+
+Add LXC_NET_NONE to known lxc_network_types, so parsing a config
+file with lxc.network.type = none does not result in failure
+(e.g. doc/examples/lxc-no-netns.conf). Options have also been
+reordered to match the enum in conf.h.
