PHP 7.0-7.3 disable_functions bypass

This exploit uses a three year old bug in PHP garbage collector to bypass disable_functions and execute a system command. It was tested on various php7.0-7.3 builds for Ubuntu/CentOS/FreeBSD with cli/fpm/apache2 server APIs and found to work reliably. Feel free to submit an issue if you experience any problems.
