This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.
This commit also includes:
* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
* `wp-admin/admin-header.php`
* `wp-admin/admin-footer.php`
* `wp-includes/version.php`

The test assumes that if a CSS file was added to `$_old_files` all three files (.css, .min.css, -rtl.min.css; it's actually missing the fourth case, -rtl.css) don't exist anymore. But this isn't always the case. The test is also incredible slow because it does three `file_exists()` checks for each file — the global contains 646 files currently.
It's important what we have in the /build directory and that's covered by `test_new_files_are_not_in_old_files_array_compiled()`.

Add a unit test to make sure the `$_old_files` array does not contain any current project files.
