[BlueOnyx:25777] 5211R - Error on upload SSL server cert

[Juerg Sommer]

Hi

I'm testing the 5211R release on a VM. When I try to upload a SSL 
certificate in "Security" - "SSL" there's an error after click on "Import".

Affected file: 
/usr/sausalito/ui/chorizo/ci4/Modules/Base/Ssl/Controllers/UploadCert.php
Affected line: 82

$system is defined as $System in line 32. After changing the variable 
name, certificate uploads works fine.

Thanks for fixing it.

Best regards
Juerg
