PHP 7.2-fpm-7 missing ioncube .so file FIX

For some reason the image `7.2-fpm-7` is missing ioncube loader, because it fails to move the file (directory not empty when using the wildcar * character).

```
[razvan@avramescu-net new]$ docker run -ti markoshust/magento-php:7.2-fpm-7 bash
app@49915c118de1:~/html$ ls -alh /usr/local/lib/php/extensions 
total 12K
drwxr-xr-x. 1 root root 4.0K Jan 24 09:28 .
drwxr-xr-x. 1 root root 4.0K Jan 24 09:28 ..
drwxr-xr-x. 1 root root 4.0K Feb  1 01:37 no-debug-non-zts-20170718
```

The change should do the trick.
