Support PHP 7.1 with bumping xdebug version

[oxyc]

See oerdnj/deb.sury.org#496.

I also reverted your merge as it wasn't actually doing any good.

[oxyc]

See #37.

Running a local test to see if this works on 7.1.

I think I'm getting a bit ahead of myself here, eek! But using the latest version is good regardless.

Tagged 2.2.2 to default to latest version, will add that role version to Drupal VM in a few min.

On debian 10 (Buster) php-xdebug installs a lot of php7.0 (like cli etc.). But I've already php7.1-cli installed and don't want to have multiple versions. If I install php-xdebug and after that I delete 7.0 and 5.6 stuff, does it lead to problems, If all depencies in 7.0 are installed in 7.1?
