Improve example linter to not lint deleted paths

Summary:
It's easy to forget to do this when writing a new lint engine (like I recently
just did), so I added it to the example to improve documentation on how to write
a lint engine. This code is copied from PhutilLintEngine (as well as many
others).

Test Plan: php -l
