Subject: [PATCH] Rewrote `bin/infection-static-analysis-plugin` to use
 `getcwd()` as a fallback

`getcwd()` is very unreliable in environments that use Windows+WSL, PHPStorm and
similar all combined together, therefore we do instead replace it with a list of
hardcoded paths where the project may be residing.

This is similar to other configurations, like `phpunit/phpunit` ( https://github.com/sebastianbergmann/phpunit/blob/c7d1d424c1c4f9efdeb75d005e65e685047a8912/phpunit#L30 )
and is much more resilient, even if very hard to test.
