Build: change the conditions for handling tests

* Debian builds no longer run the tests by default. If you want to run them, run `meson test` from the build directory.
* The option to enable or disable the tests is now removed as it's essentially pointless (since the test are only run when you run the test command).
* The tests currently use an option that's not available until meson 0.46 so the tests are not set up for previous versions. The only side effect to this is that trying to run the tests through `meson test` will do nothing on older versions.
