The core of LXC itself doesn't change when lua is enabled, the only
differences are that the following bits get built and installed:
 - /usr/lib/.../lua/VERSION/lxc/core.so (lua binding)
 - /usr/bin/lxc-top
 - /usr/share/lua/VERSION/lxc.lua (lua wrapper for core.so)

Nothing else actually changes.

Now lxc.lua itself depends on a bunch of external lua modules:
 - alt_getopt
 - lua-filesystem

For Debian/Ubuntu, the former isn't packaged which currently precludes
inclusion of lua-lxc in those distros, LXC's own daily package builds
bundle alt_getopt to workaround this. lua-filesystem is packaged in
Debian so we can just depend on that one, other distros may have to
package it though.
