lxc recipe does not install any lxc headers like lxc/lxccontainer.h

[ssbarnea]

I needed lxc in order to be able to install python module lxc-python2 but while brew install lxc installed succesfully I would nota able to detect any C/CPP headers being installed with it which obviously made impossible for the python module to compile.

$ brew reinstall -vd lxc                                                                                                                                                                                                                                             [14:16:51]

==> Summary
🍺  /usr/local/Cellar/lxc/3.7: 6 files, 17.7MB

On other platforsms like CentOS I was able to install lxc-devel in order to get the headers but I know that brew take is to avoid devel packages and to include headers with normal install. Still, in this case I I found no headers inside /usr/local/opt/lxc/ which proved to have only bin/ and few other boilerplate files.
