The typo in phpbb/filesystem/filesystem.php causes PHP warning like

[phpBB Debug] PHP Warning: in file [ROOT]/phpbb/di/container_builder.php on line 146: require(./cache/production/autoload_4335734bbdd20f586549a504dff5f80c.php): failed to open stream: No such file or directory Fatal error: require(): Failed opening required './cache/production/autoload_4335734bbdd20f586549a504dff5f80c.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/bahaiwiki/data/www/xn--80aab4a4d.kz/forum/phpbb/di/container_builder.php on line 146

The problem is here https://github.com/phpbb/phpbb/blob/3.2.x/phpBB/phpbb/filesystem/filesystem.php#L370

posic_getuid should be posix_getuid.
