Unify Vagrant and Travis-CI tests

This patch makes the tests (including the test driver) run entirely
inside Vagrant, which avoids calling the very slow `vagrant` driver many
times for running the tests. On my machine, `./test` runs in 22 seconds,
down from hundreds of seconds prior to this patch.

This also has the nice side effect of matching how the Travis CI tests
were run, so there's no need for a separate `test_travis` anymore.

Running the Tests
-----------------
Before running the tests, the virtual machine must be running. It can be
started by running `vagrant up`.
Before running the tests, you must SSH into the VM. Start it with `vagrant up`
and SSH in with `vagrant ssh`. All following commands must be run inside the
VM.
The test suite can be run by running `./test`. Selected tests can be run by
passing paths to the tests as arguments to `./test`.
First, you must install a version of Python to test against, using `pyenv
install -s {version}`. You can choose any version you like, e.g. `3.8.1`. It
isn't particularly important to test against all supported versions of Python
in the VM, because they will be tested by CI. Once you've installed a specific
version of Python, activate it with `pyenv global {version}`.
Tests can be run with a specific Python version by running `./test --version
<version>` - for example, `./test --version 3.4.3`.
The VM mounts the Dotbot directory in `/dotbot` as read-only (you can make
edits on your host machine). You can run the test suite by `cd /dotbot/test`
and then running `./test`. Selected tests can be run by passing paths to the
tests as arguments, e.g. `./test tests/create.bash tests/defaults.bash`.
To debug tests, you can prepend the line `DEBUG=true` as the first line to any
individual test (a `.bash` file inside `test/tests`). This will enable printing
stdout/stderr.
When finished with testing, it is good to shut down the virtual machine by
running `vagrant halt`.
