Update malicious_php.txt

As an additional semaphores to ```# Generic detection for compromised Bitrix CMS``` trails, which are present in ```malicious_js.txt```. Normally, files ```/bitrix/tools/check_files.php``` and ```/bitrix/gadgets/bitrix/weather/lang/ru/exec/include.php``` are absent on non-compromised Bitrix CMS-es out-of-the-box and, if they are present _by_these_specific_pathes_only_, this means, that Bitrix CMS is currently compromised. I missed to add them last time. :( This patch should fix it.
