Subject: [PATCH] Make `scanner` executable

Similar to how `composer` is an executable phar file build script is modified to produce an executable `scanner`.

Changes:

* Phar file is prepended with `#!/usr/bin/env php`
* Phar is made executable by setting `x` file attribute

It doesn't introduce any backward compatibility breaks as it's still possible to run it via `php scanner`
