Add lint check after phar is built

The initial 1.10.0-RC build (593b8dfb29)
had what looks like a bit flip of one > into a :, causing a parse error as $foo->bar became $foo-:bar in some class.

This is quite unpleasant and easy to miss as it requires including the file in question before the error is spotted.

It was quite lucky I ran a composer install with the new phar right after to do something else and spotted the error.

Linting all files covers this problem mostly, at least for the PHP files.
