Fix PHP_MAXPATHLEN check

The previous test was wrong. In fact, `PHP_MAXPATHLEN` is not the maximum length of a file, but `PHP_MAXPATHLEN - 1`. This is checked internally in the PHP source code and if the file is PHP_MAXPATHLEN characters long or longer, the error is thrown in Open-Base-Dir [1].

The problem was incompletely fixed here: laravel#50962
