This patch makes few remaining PHP development tools files
executable and adds a shebang to them.
The `#!/usr/bin/env php` shebang provides running the script via
`./script.php` and uses env to find PHP script location on the system.
At the same time it still provides running the script with a user
defined PHP location using `php script.php`. Shebang is not visible in
the output of the generated file.
