fix: use system php-league-oauth2-client instead of bundled vendor

- debian/rules: stop copying league/oauth2-client and ralouphie/getallheaders
  from vendor; only kint remains bundled (no Debian package available)
- debian/autoload.php: load League\OAuth2\Client from system autoloader,
  drop bundled getallheaders.php, simplify Kint spl_autoload_register
- debian/control: add php-league-oauth2-client to runtime Depends
