Explicitly set Arcanist path for @include_once in scripts/init/lib.php
Summary: Do the same $root dance as already existing in PhabricatorStartup.php to avoid a static code analysis error.
Test Plan:
Run PhpStan, do not get the following output anymore:
`/var/www/html/phorge/phorge/scripts/init/lib.php:12: Path in include_once() "arcanist/support/init/init-script.php" is not a file or it does not exist.`
