Install airtime in vagrant env

Uses the old installer to get LibreTime installed quick and dirty on vagrant.

It uses the `install -fIap` command that does a local install and points the apache config
directly to the local working copy mounted in /vagrant.

While we don't have fancy autoloading for libretime like the docs do, this way
it's already easy to work against a local branch.

I'm not sure if the `-I` arg to the installer also covers the python parts of libretime.
