Update deps for lxc testing.

The test scripts use in CI installed undocumented deps and correct the makefile to test on many series and in other envs like lxc.

The master branch needs ca-certificates which is implicitly provided by desktop envs, but not other envs like cloud and lxc. I removed support for quantal and raring because there is no golang or mongo that will work for them.
quantal and raring were never supported by these ppas. Saucy was supported for a few months before to reached EOL. It is nice to pretend that old series need to use PPAs to get new packages, but Ubuntu will not make them.

If the makefile wants to be checking for unsupported series, I can do so at the top and abort.
